DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.configure
Example:
RP/0/RP0/CPU0:router# configure
Step 1
Enters MPLS-TE configuration mode.mpls traffic-eng
Example:
RP/0/RP0/CPU0:router(config)# mpls traffic-eng
Step 2
Enables auto-tunnel mesh groups globally.auto-tunnel mesh
Example:
RP/0/RP0/CPU0:router(config-mpls-te)#
auto-tunnel mesh
Step 3
Specifies a timer, in minutes, after which a down auto-tunnel
mesh gets deleted whose destination was not in TE topology.
The default value for this timer is 60.
timer removal unused timeout
Example:
RP/0/RP0/CPU0:router(config-mpls-te-auto-mesh)#
timers removal unused 10
Step 4
The timer gets started when these conditions are met:
•
Tunnel destination node is removed from the topology
•
Tunnel is in down state
The unused timer runs per tunnel because the same
destination in different mesh-groups may have different
tunnels created.
Note
commit—Saves the configuration changes and remains within
the configuration session.
Use the commit or end command.
Step 5
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.
