Verifying Srp Configuration; Modifying The Source Context For Icsr - Cisco ASR 5500 System Administration Manual

Modifying the Source Context for ICSR

chassis waits for seven heart beat messages from the active chassis before it is ready to accept data. This may
cause significant delay in session manager database synchronization on the standby chassis.
You can enable an aggressive method for synchronizing the session manager database reduces recovery time
in the following scenarios:
• Standby Session Manager crash
• Packet processing card failure on Standby chassis
• Standby chassis reboot
• Temporary loss and recovery of SRP connection
The aggressive method reduces the number of heartbeat messages and amount of housekeeping information
exchanged between ICSR chassis.
The SRP Configuration mode standby database-recovery aggressive command allows you to select normal
or aggressive restoration of the SRP database.
The following command sequence enables the aggressive recovery mode:
configure
context context_name
service-redundancy-protocol
The default form of this command restores the normal mode of SRP database recovery.

Verifying SRP Configuration

Verify that your SRP contexts were created and configured properly by running the show srp info command
(Exec Mode) on each chassis.
Notes:
• 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.
