Purpose
Configures an MPLS TE backup path for a specific interface.
Exits the current configuration mode.
Exits the current configuration mode.
Configures an MPLS-TE tunnel interface.
Assigns a source address to set up forwarding on the new
tunnel.
Sets the path option to explicit with a given name (previously
configured) and assigns the path ID.
You can use the dynamic option to dynamically
Note
assign a path.
Assigns a destination address on the new tunnel.
• Destination address is the remote node's MPLS-TE
router ID.
• Destination address is the merge point between backup
and protected tunnels.
When you configure TE tunnel with multiple
Note
protection on its path and merge point is the same
node for more than one protection, you must
configure record-route for that tunnel.
Exits the current configuration mode.
