DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.configure
Example:
RP/0/RP0/CPU0:router# configure
Step 1
Configures an MPLS-TE P2MP tunnel interface.
interface tunnel-mte tunnel-id
Example:
RP/0/RP0/CPU0:router(config)# interface tunnel-mte
Step 2
101
RP/0/RP0/CPU0:router(config-if)#
Assigns a source address so that forwarding can be
performed on the new tunnel. Loopback is commonly
used as the interface type.
ipv4 unnumbered type interface-path-id
Example:
RP/0/RP0/CPU0:router(config-if)# ipv4 unnumbered
Step 3
Loopback0
Sets the destination address for tunnel-mte 10 to
140.140.140.140.
destination ip-address
Example:
RP/0/RP0/CPU0:router(config-if)# destination
Step 4
140.140.140.140
RP/0/RP0/CPU0:router(config-if-p2mp-dest)#
Disables destination 140.140.140.140 for tunnel-mte
10.
disable
Example:
RP/0/RP0/CPU0:router(config-if-p2mp-dest)#disable
