Remote neighbor logged massages " Hold timer expired " The current neighbor got down every 180 seconds, however 180 seconds (Hold timer) session was "up". But no prefixes receive. Session was being restarted cyclically, so i think that logs is consequence of session destruction.
Why the session was being restarted cyclically? That is question. >>Could both loopbacks ping each other ? Yes it is. >>Was there IP connectivity between the affected IGP neighbours when BGP went down? The IGP is OSPF and all ospf sessions were up "FULL/BDR" >>Did you see any L2 problems. What type of interfaces links the neighbors together. There were not any problem with L2. Interfaces is 1000BaseT but channel is Ethernet over SDH. And that importantly second session was up. The session with this neighbor is configured similar. But remote router is Cisco 7200, although problem session with Cisco 7600 2010/5/25 Mark Wheadon <[email protected]> > Did the neighbour show any log outputs different to what you had sent me ? > > > Was there IP connectivity between the affected IGP neighbours when BGP went > down.
