(SRP) Context, on page 272.
Step 2
Modify the source context of the core network service by applying the example configuration in Modifying the Source
Context for ICSR, on page 282.
Step 3
Modify the destination context of core network service by applying the example configuration in Modifying the Destination
Context for ICSR, on page 284.
Step 4
Optional: Disable bulk statistics collection on the standby system by applying the example configuration in Disabling

Step 6
Save your configuration as described in Verifying and Saving Your Configuration.
Configuring the Service Redundancy Protocol (SRP) Context
To configure the system to work with ICSR:
Step 1
Create the chassis redundancy context and bind it to the IP address of the primary chassis by applying the example
configuration in Creating and Binding the SRP Context, on page 273. For VPC-DI instances, this should be the IP address
of the active CF in the primary VPC-DI intance.
Step 2
Configure the chassis redundancy context with priority, chassis mode, hello interval, dead-interval and peer IP address
by applying the example configuration in Configuring SRP Context Parameters, on page 273.
Step 3
Configure the SRP context with interface parameters (including interface name, IP address and port number) for interchassis
communication by applying the example configuration in Configuring the SRP Context Interface Parameters, on page
279.
Step 4
Verify your SRP context configuration as described in Verifying SRP Configuration, on page 282.
Step 5
Save your configuration as described in Verifying and Saving Your Configuration.
