...although a little bit old... Maybe i'm thinking something wrong here, but shouldn't a single-RP router be BGP GR-capable in order to handle other than switchover cases, like a BGP process restart? BGP control-plane can go down for many reasons, why limit the GR only to dual-RP systems? Of course in that case NSF/SSO wouldn't be needed.
GR for LDP session reset uses the above approach if i remember correctly. -- Tassos Mikael Abrahamsson wrote on 22/05/2013 09:24: > On Tue, 21 May 2013, John Neiberger wrote: > >> the 7600, which the CRS immediately recognized, but the CRS continued to >> use those BGP routes until the neighbor's graceful restart timer expired. > > It's my experience that Cisco has a GR implemention that leaves some to be > desired on a lot of platforms.
