AS690 advisories
by Daniel Karrenberg 29 May '95

29 May '95

We have met with both the RA team and ANS last Tuesday. The message below is the result of these discussions. The upshot is: If you want your routes imported by ANS (AS690) you need to now: make sure you have route objects with correct advisory attruibutes in the RADB. Put those advisories in the RIPE RR. after Friday: European route objects can be removed from the RADB. AS690 advisories in the RIPE RR are sufficient to talk to ANS. July: advisory attributes will no longer be needed. This is a little easier as we expected at the RIPE meeting, so I hope everyone is happy. Daniel ------- Forwarded Message Date: Fri, 26 May 1995 16:44:47 -0400 From: Steve Heimlich <heimlich(a)ans.net> To: nanog(a)merit.edu Subject: AS690 use of multiple routing registries Folks, This note outlines changes to the ANS AS690 use of various registries which comprise the Internet Routing Registry (IRR). [RIPE gang, please forward to your mailing lists as appropriate]. Currently, the IRR consists of the following four well-known registries: the RADB, the CA*Net registry, the MCI registry, and the RIPE registry. AS690, to date, has relied exclusively on the RADB for generation of its configurations. As a result, those organizations which would naturally register in the MCI, CA*Net, or RIPE registries have been making redundant registrations in the RADB to ensure connectivity with ANS. This redundant registration has been inconvenient for many, and leads to multiple copies of route objects with inconsistent attributes. As of next week, ANS will begin to use route objects from the CA*Net, MCI, and RIPE routing registries. In order to do this, we will first create an ANS registry (containing customers of ANS) with "source: ANS" as its distinguishing attribute. Beginning with next Wednesday's AS690 config run (changed from Tuesday due to the U.S. Memorial Day holiday), we will prefer routes with AS690 advisories from these registries in the following order: ANS, CA*Net, MCI, and the RADB. Once we verify that this has succeeded, we will include the RIPE registry ahead of the RADB on next Friday's config run (i.e., ANS, CA*Net, MCI, RIPE, RADB). This method for config generation will eliminate the need for multiple registrations of singly-homed routes. Toward the end of June, we expect to have software running which will eliminate the use of AS690 advisories. This software generates an initial policy first by using registered advisories (a one-time operation). Currently, this results in a 16,000 line aut-num object for AS690. As this is somewhat unreasonable, we will be reducing the number of per-network exceptions in favor of one policy per home AS. As we approach the deployment of this capability, we will be working with peer providers on arranging mutually acceptable policies with AS690. Steve ------- End of Forwarded Message

Conflit between ICMP redirect code and default route dissemination
by Jean-Luc Richier 19 May '95

19 May '95

I have discovered a problem with the implementation of ICMP redirect in the BSD code: Due to interaction between this code and the router discovery protocol, stations may receive and keep a wrong default route, and the routers will not correct this wrong route. This leads to excessive traffic on Ethernet cables. I wish to have opinions on this problem. Which is wrong, automatic configuration of router discovery (and of any method of distributing defult routes which can be sub optimal), or the BSD routing code ? The problem was discovered with Solaris 2 staions, as they use the router discovery by default, but the Solaris system is not the cause of the problem. Description: 1/ Configuration Ethernet R1 +---+ ---------------------------------------| R | --> + connexion to station D | | +---+ using the default route +---+ +---+ + connexion to station C | A | | B | using an explicit net route +---+ +---+ | ------------ Ethernet R2 - A is a Sun station (1 Ethernet card), system Solaris 2.3 or 2.4, automatic configuration (no explicit routing information configured) - B is a Sun server (2 Ethernet cards), system Solaris 2.3 or 2.4, automatic configuration (no explicit routing information configured) - R is a router (not a Sun) running RIP but not running the Router Discovery protocol. R is connected to cable R1, and connect the site to outside. It gives access to machine C (using an explicit net route), and to machine D, using the defaut route. 2/ The problem All the packets from A to D are routed through B. Therefore each packet appears twice on the ethernet cable R1. Using snoop and netstat -r on A one can see: - A has received a default route to B. - Packets sent from A to D are sent by A to B on Ethernet, and then are sent by B to R on Ethernet. - No ICMP redirect is sent by B to A to correct the routing information. On the opposite, packets from A to C behave correctly: - the first packet from A to C is forwarded to B, then to R - On this first packet, B sends a ICMP redirect to A (redirect C through R). - the following packets from A to C are directly forwarded to R. So in this configuration, a station acquires a wrong default route, and routers fail to generate ICMP redirects to correct it. 3/ Discussion The fact that A acquires a wrong default route comes from the default configuration of both A and B (use of in.rdisc): - At boot time, B starts the in.rdisc -r daemon. (and also in.routed -s, so B receives all routes of R, including a default route) - At boot time, A starts the in.rdisc -s daemon. As B's in.rdisc daemon is active, A will use in.rdisc information and will not start in.routed. - But as R is not using the router discovery protocol, A will not discover the router R, and so will install a poor default route. One should note that : - If B sends ICMP redirects, the problem is solved : the ICMP redirect will correct the wrong route. But B does not send ICMP redirects for messages forwarded by the default route. - B knows all the correct routes received from R through RIP. It also receives the correct default routel to Internet. - Even if R is a router using rdisc protocol, there is still a problem: with standard configuration, the rdisc messages sent by R and B will have the same preference, and so there is a chance that A chooses B as default routeur. The decision not to send ICMP redirects for default routes is explicit in all the BSD codes. For example here is the comment and test in the bsd.networking code (file ip_input.c): /* * If forwarding packet using same interface that it came in on, * perhaps should send a redirect to sender to shortcut a hop. * Only send redirect if source is sending directly to us, * and if packet was not source routed (or has any options). * Also, don't send redirect if forwarding using a default route * or a route modfied by a redirect. */ #define satosin(sa) ((struct sockaddr_in *)(sa)) if (ipforward_rt.ro_rt && ipforward_rt.ro_rt->rt_ifp == ifp && (ipforward_rt.ro_rt->rt_flags & (RTF_DYNAMIC|RTF_MODIFIED)) == 0 && >>>>>> satosin(&ipforward_rt.ro_rt->rt_dst)->sin_addr.s_addr != 0 && ipsendredirects && ip->ip_hl == (sizeof(struct ip) >> 2)) { struct in_ifaddr *ia; My opinion is that ``don't send redirect if forwarding using a default route'' is a wrong decision and should be suppressed. This contradicts the RFCs on ``gateway requirements'', which do not suggest that a default route is something special. It also contradicts the philosophy of Router discovery ICMP. In order to use efficiently the net when using default routes on hosts, routers must be able to correct all routes. Default routes for a router are normal, they are a mean to lower the route information exchanged and stored. In a hierarchic routing domain, the default route is simply ``let the upper domain do the correct thing''. The problem can also appear in a site which use static default routes on hosts, when the topology changes. Suppose stations are manually configured with a default route pointing on a router B (the default router of the site). Some time after a new default router R is installed. With the current code for ICMP redirect all stations must be modified in order to correct the default route. Here are some parts of relevant RFCs: RFC1009 (Gateway requirements) A gateway will generate an ICMP Redirect if and only if the destination IP address is reachable from the gateway (as determined by the routing algorithm) and the next-hop gateway is on the same (sub-)network as the source host. Redirects must not be sent in response to an IP network or subnet broadcast address or in response to a Class D or Class E IP address. RFC1716 (Gateway requirements) Routers MUST be able to generate the Redirect for Host message (Code 1) and SHOULD be able to generate the Redirect for Type of Service and Host message (Code 3) specified in [INTERNET:8]. Routers MUST NOT generate a Redirect Message unless all of the following conditions are met: o The packet is being forwarded out the same physical interface that it was received from, o The IP source address in the packet is on the same Logical IP (sub)network as the next-hop IP address, and o The packet does not contain an IP source route option. The source address used in the ICMP Redirect MUST belong to the same logical (sub)net as the destination address. A router using a routing protocol (other than static routes) MUST NOT consider paths learned from ICMP Redirects when forwarding a packet. RFC 1256 (ICMP outer discovery message) The router discovery messages do not constitute a routing protocol: they enable hosts to discover the existence of neighboring routers, but not which router is best to reach a particular destination. If a host chooses a poor first-hop router for a particular destination, it should receive an ICMP Redirect from that router, identifying a better one. It has been suggested that, when the preference level of an address has not been explicitly configured, a router could set it according to the metric of the router's "default route" (if it has one), rather than defaulting it to zero as suggested above. ...... ....... Such a strategy might reduce the amount of ICMP Redirect traffic on some links by making it more likely that a host's first choice router for reaching an arbitrary destination is also the best choice. On the other hand, Redirect traffic is rarely a significant load on a link, and there are some cases where such a strategy would result in more Redirect traffic, not less (for example, on links from -- Jean-Luc RICHIER (Jean-Luc.Richier(a)Imag.Fr richier(a)imag.fr) LGI, IMAG-CAMPUS, BP 53, F-38041 GRENOBLE Cedex 9 Tel : (33) 76 82 72 32 Fax : (33) 76 44 66 75

The Top 20 and some deltas
by Tony Bates 25 Jan '95

25 Jan '95

This is an auto-generated mail on Wed Jan 25 21:10:00 MET 1995 As stated above this is auto-generated so it is not checked before it leaves my workstation. This is a list of the "Top 20" players who if CIDRizing at the AS level could make a significant gain in the size of Internet routing tables. This may be an over-estimation but it is hoped that this can act as an incentive for the "Top 20" and others to look at their CIDR capability. This report is available as: ftp://ftp.ripe.net/cidr/stats/Top-20.25Jan95 The current (and of course this one today) report is always accessible as: ftp://ftp.ripe.net/cidr/stats/Top-20 A full summary of all the ASes seen in the Internet can be seen by looking in: ftp://ftp.ripe.net/cidr/stats/AS* Please also find a summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does some indication of ASes participating in CIDR. More information can be found in: ftp://ftp.ripe.net/cidr/stats/Delta.* Also, for a short time this gives details of any possibly interesting aggregates currently seen in the routing. Interesting here means not a aggregate made as a set of classful routes. This a daily snapshot of changes in classfull routes being withdrawn and added. the deltas are calculated over a rolling 7 day period. Please bear in mind this is purely a "snapshot" and a large flucuation could be caused by a connectivity problem for example. However, this does give some indication of service providers that are moving to classless routing.

The Top 20 and some deltas

This is an auto-generated mail on Wed Jan 18 21:10:00 MET 1995 As stated above this is auto-generated so it is not checked before it leaves my workstation. This is a list of the "Top 20" players who if CIDRizing at the AS level could make a significant gain in the size of Internet routing tables. This may be an over-estimation but it is hoped that this can act as an incentive for the "Top 20" and others to look at their CIDR capability. This report is available as: ftp://ftp.ripe.net/cidr/stats/Top-20.18Jan95 The current (and of course this one today) report is always accessible as: ftp://ftp.ripe.net/cidr/stats/Top-20 A full summary of all the ASes seen in the Internet can be seen by looking in: ftp://ftp.ripe.net/cidr/stats/AS* Please also find a summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does some indication of ASes participating in CIDR. More information can be found in: ftp://ftp.ripe.net/cidr/stats/Delta.* Also, for a short time this gives details of any possibly interesting aggregates currently seen in the routing. Interesting here means not a aggregate made as a set of classful routes. This a daily snapshot of changes in classfull routes being withdrawn and added. the deltas are calculated over a rolling 7 day period. Please bear in mind this is purely a "snapshot" and a large flucuation could be caused by a connectivity problem for example. However, this does give some indication of service providers that are moving to classless routing.

The Top 20 and some deltas
by Tony Bates 04 Jan '95

04 Jan '95

This is an auto-generated mail on Wed Jan 4 21:10:01 MET 1995 As stated above this is auto-generated so it is not checked before it leaves my workstation. This is a list of the "Top 20" players who if CIDRizing at the AS level could make a significant gain in the size of Internet routing tables. This may be an over-estimation but it is hoped that this can act as an incentive for the "Top 20" and others to look at their CIDR capability. This report is available as: ftp://ftp.ripe.net/cidr/stats/Top-20.04Jan95 The current (and of course this one today) report is always accessible as: ftp://ftp.ripe.net/cidr/stats/Top-20 A full summary of all the ASes seen in the Internet can be seen by looking in: ftp://ftp.ripe.net/cidr/stats/AS* Please also find a summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does some indication of ASes participating in CIDR. More information can be found in: ftp://ftp.ripe.net/cidr/stats/Delta.* Also, for a short time this gives details of any possibly interesting aggregates currently seen in the routing. Interesting here means not a aggregate made as a set of classful routes. This a daily snapshot of changes in classfull routes being withdrawn and added. the deltas are calculated over a rolling 7 day period. Please bear in mind this is purely a "snapshot" and a large flucuation could be caused by a connectivity problem for example. However, this does give some indication of service providers that are moving to classless routing.

The Top 20 and some deltas
by Tony Bates 28 Dec '94

28 Dec '94

This is an auto-generated mail on Wed Dec 28 21:10:01 MET 1994 As stated above this is auto-generated so it is not checked before it leaves my workstation. This is a list of the "Top 20" players who if CIDRizing at the AS level could make a significant gain in the size of Internet routing tables. This may be an over-estimation but it is hoped that this can act as an incentive for the "Top 20" and others to look at their CIDR capability. This report is available as: ftp://ftp.ripe.net/cidr/stats/Top-20.28Dec94 The current (and of course this one today) report is always accessible as: ftp://ftp.ripe.net/cidr/stats/Top-20 A full summary of all the ASes seen in the Internet can be seen by looking in: ftp://ftp.ripe.net/cidr/stats/AS* Please also find a summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does some indication of ASes participating in CIDR. More information can be found in: ftp://ftp.ripe.net/cidr/stats/Delta.* Also, for a short time this gives details of any possibly interesting aggregates currently seen in the routing. Interesting here means not a aggregate made as a set of classful routes. This a daily snapshot of changes in classfull routes being withdrawn and added. the deltas are calculated over a rolling 7 day period. Please bear in mind this is purely a "snapshot" and a large flucuation could be caused by a connectivity problem for example. However, this does give some indication of service providers that are moving to classless routing.

The Top 20 and some deltas
by Tony Bates 21 Dec '94

21 Dec '94

This is an auto-generated mail on Wed Dec 21 21:10:01 MET 1994 As stated above this is auto-generated so it is not checked before it leaves my workstation. This is a list of the "Top 20" players who if CIDRizing at the AS level could make a significant gain in the size of Internet routing tables. This may be an over-estimation but it is hoped that this can act as an incentive for the "Top 20" and others to look at their CIDR capability. This report is available as: ftp://ftp.ripe.net/cidr/stats/Top-20.21Dec94 The current (and of course this one today) report is always accessible as: ftp://ftp.ripe.net/cidr/stats/Top-20 A full summary of all the ASes seen in the Internet can be seen by looking in: ftp://ftp.ripe.net/cidr/stats/AS* Please also find a summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does some indication of ASes participating in CIDR. More information can be found in: ftp://ftp.ripe.net/cidr/stats/Delta.* Also, for a short time this gives details of any possibly interesting aggregates currently seen in the routing. Interesting here means not a aggregate made as a set of classful routes. This a daily snapshot of changes in classfull routes being withdrawn and added. the deltas are calculated over a rolling 7 day period. Please bear in mind this is purely a "snapshot" and a large flucuation could be caused by a connectivity problem for example. However, this does give some indication of service providers that are moving to classless routing.
