Monitoring BFD Connection for ICSR
For ICSR configurations, the following command sequence initiates monitoring of the connection between the primary
chassis and the BFD neighbor in the specified context. If the connection drops, the standby chassis becomes active.

monitor bfd context context_name { ipv4_address | ipv6_address } {
chassis-to-chassis | chassis-to-router }
chassis-to-chassis | chassis-to-router }
Notes:
ipv4 _address | ipv6_address defines the IP address of the BFD neighbor to be monitored, entered using IPv4
dotted-decimal or IPv6 colon-separated-hexadecimal notation
chassis-to-chassis enables BFD to run between primary and backup chassis on non-SRP links.
chassis-to-router enables BFD to run between chassis and router.

Chassis-to-Chassis BFD Monitoring for ICSR
An operator can configure BFD to more quickly advertise routes during an ICSR switchover. This solution
complements the feature that allows the advertising of BGP routes from a Standby ICSR chassis. The overall goal is to
support more aggressive failure detection and recovery in an ICSR configuration when implementing of VoLTE.
