MPLS TE Configuration Example 1407
[RouterA] interface pos 5/1
[RouterA-POS5/1] mpls
[RouterA-POS5/1] mpls te
[RouterA-POS5/1] mpls rsvp-te
[RouterA-POS5/1] quit

Create an MPLS TE tunnel on Router A
# Configure the MPLS TE tunnel carried on the primary LSP.
[RouterA] interface tunnel 3
[RouterA-Tunnel3] ip address 9.1.1.1 255.255.255.0
[RouterA-Tunnel3] tunnel-protocol mpls te
[RouterA-Tunnel3] destination 3.3.3.9
[RouterA-Tunnel3] mpls te tunnel-id 10
# Enable hot LSP backup.
[RouterA-Tunnel3] mpls te backup hot-standby
[RouterA-Tunnel3] mpls te commit
[RouterA-Tunnel3] quit
Perform the display interface tunnel command on Router A. You can find that
Tunnel3 is up.

Verify the configuration
Perform the display mpls te tunnel command on Router A. You can find that
two tunnels are present with the outgoing interface being Ethernet 1/0 and POS
5/1 respectively. This indicates that a backup CR-LSP was created upon creation of
the primary CR-LSP.
[RouterA] display mpls te tunnel
LSP-Id Destination In/Out-If Name
1.1.1.9:6 3.3.3.9 -/Eth1/0 Tunnel3
1.1.1.9:2054 3.3.3.9 -/POS5/1 Tunnel3
Perform the display mpls te tunnel path command on Router A to identify the
paths that the two tunnels traverse:
