Modifying the Source Context for ICSR

• The interval is specified as an integer divisible by 15 in the range from 30 through 1440 (Default = 45
Modifying the Source Context for ICSR
To modify the source context of core service:
Step 1
Add the Border Gateway Protocol (BGP) router AS-path and configure the gateway IP address, neighbor IP address,
remote IP address in the source context where the core network service is configured, by applying the example
configuration in
Step 2 Configure the service redundancy context with the BGP neighbor context and IP address to monitor the BGP link activity
by applying the example configuration in
Step 3 Verify your BGP context configuration by following the steps in
Step 4
Save your configuration as described in Verifying and Saving Your Configuration.

Configuring BGP Router and Gateway Address

Use the following example to create the BGP context and network addresses.
configure
context source_ctxt_name
Notes:
• source_ctxt_name is the context where the core network service is configured.

Configuring the SRP Context for BGP

Use the following example to configure the BGP context and IP addresses in the SRP context.
configure
context srp_ctxt_name
neighbor_ip_address can be entered in IPv4 dotted-decimal or IPv6 colon-separated-hexadecimal notation.
Multiple IP addresses can be added per context as IPv4 and/or IPv6 IP addresses.
An ICSR failover is triggered when all BGP peers within a context are down.
Optionally, you can configure SRP peer groups within a context. ICSR failover would then occur if all peers
within a group fail. This option is useful in deployments in which a combination of IPv4 and IPv6 peers are
spread across multiple paired VLANs, and IPv4 or IPv6 connectivity is lost by all members of a peer group.
