Symptoms

After BGP peer with graceful restart goes down and comes up again, some of the BGP routes are not being advertised anymore.
When BGP graceful restart configured after ClusterXL failover, some BGP advertised routes are missing.

Cause

Upon a peering reset the external queue of routes sent to the peer were not completely cleared, so this made routed think that the route is already advertised to the peer. This resulted in some routes being not advertised to the peer.
