Chapter 34 Configuring MPLS, MPLS VPN, MPLS OAM, and EoMPLS
Configuring MPLS Traffic Engineering and Fast Reroute
Enter the no forms of the commands to remove the configured MPLS tunnels. Enter the no ip
explicit-path name global configuration command to disable IP explicit paths.
Configuring the Routing Protocol for MPLS TE
Beginning in privileged EXEC mode, follow these steps to configure IS-IS or OSPF for MPLS traffic
engineering:
To remove the traffic engineering router identifier, use the no mpls traffic-eng router-id command.
Configuring TE Fast Reroute
Before or after entering the commands described in these procedures, you must enable the MPLS traffic
engineering tunnel capability globally on the tunnel routers by entering the mpls traffic-eng tunnels
global and interface configuration commands. For information about the commands for MPLS TE fast
reroute, see this URL:
