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
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
activity by applying the example configuration in
Step 3
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
router bgp AS_num
network gw_ip_address
neighbor neighbor_ip_address remote-as AS_num
end
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
service-redundancy-protocol
monitor bgp context source_ctxt_name neighbor_ip_address
end
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.
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.
