interface. Enter the no rsvp bandwidth interface configuration command to return to the default.

Configuring an MPLS TE Tunnel

Beginning in privileged EXEC mode, follow these steps to configure an MPLS traffic engineering
tunnel. The configured tunnel has two path setup options—a preferred explicit path and a backup
dynamic path.

Configuring MPLS Traffic Engineering and Fast Reroute
Purpose
Enable RSVP for IP on an interface and the maximum amount of
bandwidth, in kb/s, that may be allocated by RSVP flows. The range
is from 1 to 10000000. The default is 75% of the link bandwidth.
(Optional) Enable Hello signalling on the interface.
Return to privileged EXEC mode.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Enter interface configuration mode for a tunnel interface.
Configure the tunnel source address to be the IP address of the
loopback0 interface. The command is not effective until loopback0
is configured with an IP address.
Specify the destination for a tunnel.
Set the encapsulation mode of the tunnel to MPLS traffic
engineering.
Specify that the Interior Gateway Protocol (IGP) should use the
tunnel (if the tunnel is up) in its enhanced shortest path first (SPF)
calculation.
Configure the setup and reservation priority for an MPLS TE tunnel.
Configure the bandwidth, in kb/s per second, set aside for the MPLS
traffic engineering tunnel. The range is from 1 to 4294967295 kb/s.
The default is 0.
(Optional) Enable this option if you are configuring fast reroute.
Configure a named IP explicit path.
Configure a backup path to be dynamically calculated from the
traffic engineering topology database.
Return to global configuration mode.
Specify the IP explicit path name, and enter IP explicit path
configuration mode. An IP explicit path is a list of IP addresses, each
representing a node or link in the explicit path.
Specify the next IP address in the explicit path.
Specify the second IP address in the explicit path.
