Enabling LDP on Auto-Tunnel Mesh
Perform this task to enable LDP on auto-tunnel mesh group.
SUMMARY STEPS
1.
configure
2.
mpls ldp
3.
traffic-eng auto-tunnel mesh
4.
groupidall
5.
Use the commit or end command.
DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.configure
Example:
RP/0/RP0/CPU0:router# configure
Step 1
Enters MPLS LDP configuration mode.mpls ldp
Example:
RP/0/RP0/CPU0:router(config-ldp)# mpls ldp
Step 2
Enters auto-tunnel mesh configuration mode. You can configure
TE auto-tunnel mesh groups from this mode.
traffic-eng auto-tunnel mesh
Example:
RP/0/RP0/CPU0:router(config-ldp-te-auto-mesh)#
traffic-eng auto-tunnel mesh
Step 3
Configures an auto-tunnel mesh group of interfaces in LDP.
You can enable LDP on all TE meshgroup interfaces or you can
groupidall
Example:
RP/0/RP0/CPU0:router(config-ldp-te-auto-mesh)#
group all
Step 4
specify the TE mesh group ID on which the LDP is enabled.
The range of group ID is from 0 to 4294967295.
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.
