ICSR and SRP Groups
BGP is employed with Interchassis Session Recovery (ICSR) configurations linked via Service Redundancy Protocol
(SRP). By default an ICSR failover is triggered when all BGP peers within a context are down.
(SRP). By default an ICSR failover is triggered when all BGP peers within a context are down.
Optionally, you can configure SRP peer groups within a context. ICSR failover would then occur if all peers within a
group fail. This option is useful in deployments in which a combination of IPv4 and IPv6 peers are spread across
multiple paired VLANs, and IPv4 or IPv6 connectivity is lost by all members of a peer group.
