Cisco ASR 9000 Series Configuration Guidelines

Example:
RP/0/RSP0/CPU0:router (config-l2vpn)# nsr
Enables L2VPN nonstop routing.
Step 4 logging nsr
Example:
RP/0/RSP0/CPU0:router (config-l2vpn)# logging nsr
Enables logging of NSR events.
Step 5 Use the commit or end command.
commit - Saves the configuration changes and remains within the configuration session.
end - Prompts user to take one of these actions:
• Yes - Saves configuration changes and exits the configuration session.
• No - Exits the configuration session without committing the configuration changes.

stateful LDP feature, you must explicitly configure LDP NSR to synchronize label information between active
and standby LDPs.
