Configure an MPLS TE tunnel on Router A:
# Configure the MPLS TE tunnel interface Tunnel 0.
[RouterA] interface tunnel 0 mode mpls-te
[RouterA-Tunnel0] ip address 6.1.1.1 255.255.255.0
# Specify the tunnel destination address as the LSR ID of Router C.

Create a static CRLSP:
# Configure Router A as the ingress node of the static CRLSP, and specify the next hop
address as 2.1.1.2, outgoing label as 20, and required bandwidth as 2000 kbps.

Verifying the configuration
# Execute the display interface tunnel command on Router A. The output shows that the tunnel
interface is up.
