DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.configure
Example:
RP/0/RP0/CPU0:router# configure
Step 1
Configures an MPLS-TE tunnel interface.
interface tunnel-te tunnel-id
Example:
RP/0/RP0/CPU0:router# interface tunnel-te 1
Step 2
Assigns a destination address on the new tunnel.
destination ip-address
Step 3
Example:
RP/0/RP0/CPU0:router(config-if)# destination
The destination address is the remote node’s MPLS-TE router
ID.
192.168.92.125
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
Step 4
unnumbered Loopback0
Sets the path option to dynamic and assigns the path ID.
path-option preference - priority dynamic
Example:
RP/0/RP0/CPU0:router(config-if)# path-option
Step 5
l dynamic
Sets the CT0 bandwidth required on this interface. Because
the default tunnel priority is 7, tunnels use the default TE class
map (namely, class-type 1, priority 7).
signalled- bandwidth {bandwidth [class-type ct ] |
sub-pool bandwidth}
Example:
RP/0/RP0/CPU0:router(config-if)#
Step 6
signalled-bandwidth 100
commit—Saves the configuration changes, and remains within
the configuration session.
Use the commit or end command.
Step 7
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.
