Step 3 interface type interface-path-id
Example:
RP/0/RP0/CPU0:router(config-mpls-te)#
interface POS0/6/0/0
Step 4
flooding-igp ospf instance-id area area-id
Example:
RP/0/RP0/CPU0:router(config-mpls-te-if)#
flooding-igp ospf 0 area 1
Step 5 switching key value [encoding encoding type]
Example:
RP/0/RP0/CPU0:router(config-mpls-te-if)#
switching key 1 encoding ethernet
Step 6 switching key value [capability {psc1 | lsc | fsc} ]
Example:
RP/0/RP0/CPU0:router(config-mpls-te-if)#
switching key 1 capability psc1
Step 7 Use the commit or end command.

Configuring Persistent Interface Index

Perform this task to preserve the LMP interface index across all interfaces on the router.

Purpose
Enters MPLS-TE interface configuration mode and enables traffic
engineering on a particular interface on the originating node.
Specifies the IGP OSPF interface ID and area where the TE links
are to be flooded.
Specifies the switching configuration for the interface and enters
switching key mode where you will configure encoding and
capability.
The recommended switch key value is
Note
0.
Specifies the interface switching capability type. The
recommended switch capability type is psc1.
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 session, without
committing the configuration changes.
