 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. 



 

 enables BFD to run between chassis and router. 

Save your configuration as described in the Verifying and Saving Your Configuration chapter. 

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: 



 

  



 

  



 

  



 

  



 

  



 

  

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 

  

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. 

Enable this feature in association with BFD chassis-to-chassis monitoring to support more aggressive ICSR failure 
detection times.
