Configuring L3VPN over GRE
Example:
RP/0/RP0/CPU0:router(config-ldp)# graceful-restart forwarding-state-holdtime 300
Defines the time that the neighbor should retain the MPLS forwarding state during a recovery.
Step 10
holdtime seconds
Example:
RP/0/RP0/CPU0:router(config-ldp)# holdtime 90
Configures the hold time for an interface.
Step 11
neighbor ip-address
Example:
RP/0/RP0/CPU0:router(config-ldp)# neighbor 10.1.1.0
Defines a neighboring router.
Step 12
interface tunnel-ip number
Example:
RP/0/RP0/CPU0:router(config-ldp)# interface tunnel-ip 4
Enters tunnel interface configuration mode.
• number is the number associated with the tunnel interface.
Step 13
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.
• Cancel - Remains in the configuration mode, without committing the configuration changes.
