Why not look at the exiting BGP policy tool we have today in 12.0S, 12.2S, Junos, and IOX to see if it can be a configurable policy - if it is not - draft a new feature description. You got both vendor here. I've done this in other SP Security forums. There are something on this list that are interesting ideas - but out of context of how the various flavors of routing software in the industry works. There are other things - like this routing policy idea - that can be walked through to the point where we have new tools added to vendor's security toolkit. > -----Original Message----- > From: Mike Hughes [mailto:mike@linx.net] > Sent: Wednesday, October 12, 2005 7:37 AM > To: Barry Greene (bgreene) > Cc: routing-wg(a)ripe.net > Subject: RE: [routing-wg]Routing Aggregation Policy > > --On 12 October 2005 06:41 -0700 "Barry Greene (bgreene)" > <bgreene(a)cisco.com> wrote: > > > How would you enforce a policy like this (Other than peer > pressure)? > > Okay, judging from some of the messages I've had privately, > as well as this one, I obviously didn't make myself clear. > > As an enforceable policy this FAILED. > > The LINX members voted to reject any sort of interference > in/policing of their routing, for a number of reasons. > > Once it had failed, I was given an action by the LINX General > Meeting to take the bones of failed policy, as it stood at > the time of the rejection, and offer it to the RIPE > routing-wg as the basis for a Best Practice document, which > by nature is non-enforceable. > > Cheers, > Mike > -- > Mike Hughes Chief Technical Officer London Internet Exchange > mike(a)linx.net http://www.linx.net/ > "Only one thing in life is certain: init is Process #1" >

"Auto-De-Peer this neighbor if the > aggregation ratio is bad"? People where saying the same thing when we started the Bogon Prefix filtering project. The side effect of the Bogon project is a limit on the de-aggregation. Strict and Loose both have limits on the largest prefix allowed through. That is why we do not see /28s all over the place. So if you look at this policy idea and think - how would I like BGP code to filter to enforce this. You add it into the RIPE document as a recommendation to the vendors. The vendors then go out and add the filtering capabilities to match the RIPE policy.

[routing-wg]Routing Aggregation Policy
by Mike Hughes 12 Oct '05

12 Oct '05

Hi folks, Joao asked me to forward some background to an item that I will do on Thursday. This is the last draft of the defunct Route Aggregation Policy that was formulated by the LINX Council/Members, before it was rejected as a "policy" by the LINX General Meeting in August. I took an action from the LINX Membership at that meeting to donate what we had to the RIPE community for re-formulation into a best practice document. I'll give you some more background during Thursday's WG meeting, but for now, here's the draft itself, as it stood at the point of the rejection as an enforced policy by the Membership: --------------------------------------------------------------------------- Revised Route Aggregation Policy -------------------------------- A LINX member shall announce no more than (N * 2) + 3 prefixes, where N is the number of maximally aggregatable prefixes that could originate from the AS under ideal conditions. Prefixes are aggregatable if: 1. They have the same AS path 2. They are adjacent 3. They are of equal size and are 2**N in size where N is an integer 4. They start on "power of two" boundaries 5. After aggregation, the result starts on a "power of two" boundary In order to determine maximal aggregation such prefixes shall be aggregated, and the criteria above applied again. This process shall be repeated until no further prefixes can be aggregated. This final number of prefixes is the maximally aggregatable prefixes announced from that AS. In order to ensure neutrality and to guard against bias in the measurement, announcements shall be observed at several locations, decided from time to time by the LINX Council. For those members with large amounts of address space, for prefixes smaller than /16, deaggregates up to /16 will be permitted without penalty and all such announcements will be considered as one, for the purposes of calculating the metric. For example, a member with a /14 will be able to announce this as 4 /16s and this will be counted as 1 announcement. Examples of aggregation calculations ------------------------------------ Example #1 If you currently advertise the following prefixes from your ASN: 10.123.4.0/24 10.123.5.0/24 10.123.6.0/23 On the first aggregation pass, you could aggregate the first two prefixes into a single /23, leaving you with: 10.123.4.0/23 10.123.6.0/23 If you then aggregate again, you'll be able to further aggregate these together into a single /22, leaving you with: 10.123.4.0/22 However, if you were advertising the following prefixes: 10.201.5.0/24 10.201.6.0/24 then these are already aggregated as far as possible, as although they are consecutive, and it appears that they could be replaced with a single /23, the first prefix, 10.201.5.0/24 is not on a /23 boundary. ---------------------------------------------------------------------------- Obviously, it will need re-drafting to be more BCP-like, rather than a policy, and don't ask me what happened to Examples 2 and 3 ;). Thanks, Mike -- Mike Hughes Chief Technical Officer London Internet Exchange mike(a)linx.net http://www.linx.net/ "Only one thing in life is certain: init is Process #1"
