Did it drop at about 5:15am? We saw a hit on our fiber on that span starting at that time. We have since recovered, but still see more attenuation than normal.

I can look at who has a session up before, make the change, and see if anyone's session goes down. If so, I can contact them specifically.

We are looking at this on QCIX as well.

Re: BGP ADD-PATH capability

by Michael Hare

Ack'ing this is a negotiated feature, buyer beware for those who turn it on and are using prefix-limits on their BGP sessions. I've used add-path on JunOS and on that platform you optionally add a 'path-count' function on the TX side for intra ASN stuff. In the bird implementation the behavior is "all" routes. Is there a graph or can you provide a one time count of the current RIB sizes on the RS? I am in favor adding the feature, but I’m not sure if 1 week spacing is enough to prove stability. But I’m known to be nervous.

BGP ADD-PATH capability

by Richard Laager

I propose that MICE enable BGP ADD-PATH capability (RFC 7911) on the route servers (in TX mode only). This is negotiated BGP capability, so we do not need any per-participant setting for it. ADD-PATH is useful if the best path route is being filtered but another route would not be. We discussed adding this at a UG meeting years ago. There are other IXPs that have this enabled. For example, this one: https://www.bcix.de/ixp/content/0/route-servers In terms of timeline, I propose something like this: * January 9: Enable it on Route Server 1. * January 16: Enable it on Route Server 2.
