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

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.

You must configure the following features for chassis-to-chassis BFD monitoring in ICSR configurations:
Enable Primary Chassis BFD Monitoring
You must enable monitoring of the connection between the primary chassis and specified BFD neighbors. If the
connection drops, the standby chassis becomes active. For more information, see
connection drops, the standby chassis becomes active. For more information, see
Set BFD to Ignore ICSR Dead Interval
The SRP Configuration mode bfd-mon-ignore-dead-interval command causes the standby ICSR chassis to ignore the
dead interval and remain in the standby state until all the BFD chassis-to-chassis monitors fail.
