Howdy! A question of interest to me, currently, is whether it's normal for providers to cause BGP flaps to their customers nightly... This seems, in my case, to be the provider PROBABLY updating prefix-filters on my session(s).
Particularly AS56554 is currently getting v4/v6 transit from 2 providers, one of which we have 2 links toward. That provider appears to flap both of our ipv6 (only) bgp peers each night at about the same time each night. This smells like: "filter updates', but something that's different than the v4 filter update? (or perhaps they have no v4 filtering to update?)
In the end, should customers expect nightly (or on a regular cadence) to see their sessions bounce? It hasn't been my experience in other situations...
This seems unusual, perhaps a bug in their tooling or their config where it’s doing a hard clear vs soft clear on the session?
This was sort of my thinking, but I was unsure if there was some new process and/or bug which other edge-y folk were dealing with of late. I can/will ask the provider in question (a local apac provider) if they are aware of the actions they are taking.
