[routing-wg]Representation of four byte AS numbers.
by Rob Evans 20 Oct '08

20 Oct '08

Hi all, At some point in the coming week I expect to see a new policy proposal hit the policy-announce and address-policy mailing lists that we might want to be aware of here. In past working group sessions we've already discussed the benefits and disadvantages of the various methods of representing 32 bit ASNs (i.e. 'asplain,' 'asdot'). There is now an internet-draft recommending asplain (which is just a single 32 bit integer) in last call at the IETF which can be obtained from the following URL: http://www.ietf.org/internet-drafts/draft-ietf-idr-as-representation-01.txt A related policy proposal reached consensus at the last APNIC meeting and is now in last call there: http://www.apnic.net/policy/proposals/prop-065-v001.html Whilst we already have a presentation on experiences of using a 32 bit ASN scheduled for the Routing working group session, the policy is being discussed in the Address Policy working group. At the moment it will be presented during the session just before lunch on Tuesday morning. At the same time there will also be a presentation on the proposal for certification of PA resources, which you may also be interested in. All the best, Rob

Well, if the AS-set doesn't fit, that's a problem. But it isn't necessarily the case that simply because an AS that gets, say, RIPE addresses is transcontental means that it can't be part of a "RIPE" aggregate. One would have to sit down and see how bad the paths are relative to the RIB savings. I don't suppose anyone has done such a study?

[routing-wg]Request for references to recent studies on deployment of route flap damping
by Benno Overeinder 23 Sep '08

23 Sep '08

Hi, For some modeling and simulation work, we are interested in recent studies on the deployment of route flap damping. For example, similar to the study performed by Greg Hankins from Force10 and others, whom have presented survey results about BGP usage on RIPE56 (http://www.ripe.net/ripe/meetings/ripe-56/presentations/eix/Hankins-Peering…). Unfortunately, route flap damping was not addressed in this study. Are there any large carrier networks (tier 1 and large tier 2 networks) configured with route flap damping? Are there any references to recent studies on the deployment of route flap damping by network operators? Thanks, -- Benno Overeinder P.S. Similar message has been sent to IDR email list of the IETF. Sorry for duplicates. -- Benno J. Overeinder NLnet Labs http://www.nlnetlabs.nl/
