Re: BGP Update Report [ In reply to ]
So, this week, I actually read the update report. Noting the stats below (..a flap/update once per minute? please, fix your CPE router), I have but one humble request:

Could the settlement-free members of the DFZ please consider re-enabling route-flap dampening towards customers?

Thanks,

The problem is that unless one is holding customer routes in a
seperate VRF and dampen them there or take similar steps to
segment, dampening leads directly to blackholes. Even in that
case, failover within that VRF wouldn't work, as all
implementations I've seen attack the prefix as the problem instead
of the path vector. Bye-bye alternate paths.

I guess what I'm hinting at is precisely something finer-grained (path not prefix), as you suggest. Per-neighbor enabled, versus "entire bgp RIB" would be preferred. I'm also interested in the *chronic* nature of these apparent instabilities. An average of one flap per minute could imply that the end-site is not getting allot of useful TCP moved, and as such, after something on the (n)-hour timescale, perhaps it's worth suppressing it.

So, I'd ask for a long-timescale dampening function, indexed against per-path, and enforced per neighbor. Perhaps as-path lists could be combined with relaxed timers on existing implementations to achieve this today (in a VRF target/context).

It's not just AS_PATH, a lot of the reason so many duplicate updates occur
(nearly 50% of all updates at times, and often more during the busiest times)
is because on the other end implementations don't keep egress advertisement state
per attribute (e.g., if cluster_list length just triggered an internal transition
then a new update is sent to external peers with no new information because the
determining internal attributes are stripped before transmitting the new update),
yet those *prefixes* might well be suppressed as a result of the implementation
and/or network architecture on the other end of the BGP connection.

Then you couple what Joe was pointing out, where intermediate nodes with
consistently unstable links or "paths" result in penalizing an entire prefix,
not just the unstable paths, and it makes for more brokenness than benefit
when route flap damping is employed.

It's not that people haven't studied and understand why this occurs, the
issue is that implementation optimizations seem to always win out today over
systemic state effects (i.e., that "be conservative in what you send" thing
doesn't seem to apply in practice, unfortunately).

might some of this be that the implementations use router-id to fill in
an unconfigured rr cluster-id?

Yep! So intermediate nodes in an iBGP topology with varying cluster
IDs per RR with a common client set can certainly result in duplicate
eBGP updates (not to mention lots of *useless* adj-RIB-In memory on
those RRs for storing routes that are completely useless and would
otherwise be discarded).

That said, even with common cluster IDs within a client set, and even
a single level (or completely flat) iBGP hierarchy, coupled with any
jitter, variable propagation delay along a path, asymmetric or not,
depending on transport connection dynamics, or variance in update arrival
rates, and BGP speaker MRAI interactions with each, all can result in
these duplicate updates at egress, and subsequent suppression via flap
damping if employed. And, of course, this is compounded by external
interconnection denseness on ingress and even non-adjacent downstream
ASNs.

I.e., there's room for protocol, implementation, and network architecture
variables here, and operators should expressly factor systemic effects of
each in their operating environment - they can have considerable impact.
