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.
config
context context_name
chassis-to-router }
Notes:
• ipv4 _address | ipv6_address defines the IP address of the BFD neighbor to be monitored, entered using
• 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.
You must configure the following features for chassis-to-chassis BFD monitoring in ICSR configurations:
router ospf
bfd-all-interfaces
interface interface_name
broadcast
ip ospf bfd
service-redundancy-protocol
monitor bfd context context_name { ipv4_address | ipv6_address } { chassis-to-chassis |
IPv4 dotted-decimal or IPv6 colon-separated-hexadecimal notation
