No. There should be no reason to bounce the session. Do you have soft updates turn on? -mel via cell

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... -chris
