7. Configure an MPLS TE tunnel:

# On Router A, configure MPLS TE tunnel interface Tunnel 1, specify the tunnel destination address

as the LSR ID of Router D, configure MPLS TE to use RSVP-TE to establish the tunnel, assign 2000

kbps bandwidth to the tunnel, and specify the explicit path atod for the tunnel.

[RouterA] interface tunnel 1 mode mpls-te

[RouterA-Tunnel1] ip address 7.1.1.1 255.255.255.0

[RouterA-Tunnel1] destination 4.4.4.9

[RouterA-Tunnel1] mpls te signaling rsvp-te

[RouterA-Tunnel1] mpls te bandwidth 2000

[RouterA-Tunnel1] mpls te path preference 5 explicit-path atod

[RouterA-Tunnel1] quit

8. Configure a static route on Router A to direct the traffic destined for subnet 30.1.1.0/24 to MPLS

TE tunnel 1:

[RouterA] ip route-static 30.1.1.2 24 tunnel 1 preference 1

Verifying the configuration

# Execute the display interface tunnel command on Router A. The output shows that the tunnel interface

is up.

[RouterA] display interface tunnel 1

Tunnel1 current state: UP

Line protocol current state: UP

Description: Tunnel1 Interface

The Maximum Transmit Unit is 64000
