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

Creating and Binding the SRP Context
Use the example below to create the SRP context and bind it to primary chassis IP address:
Important:
ICSR is configured using two systems. Be sure to create the redundancy context on both systems.
CLI commands must be executed on both systems. Log onto both chassis before continuing. Always make configuration
changes on the primary chassis first. Before starting this configuration, identify which chassis to configure as the
primary and use that login session.

bind address ip_address
end
Notes:
ICSR should be configured and maintained in a separate context.
Be sure to bind the local IP address to the primary chassis. When configuring the backup chassis, be sure to bind
the local IP address to the backup chassis.
