5. Configure a bypass tunnel on Router B, the PLR:

# Configure an explicit path for the bypass tunnel.

[RouterB] explicit-path by-path

[RouterB-explicit-path-by-path] nexthop 3.2.1.2

[RouterB-explicit-path-by-path] nexthop 3.3.1.2

[RouterB-explicit-path-by-path] nexthop 3.3.3.3

[RouterB-explicit-path-by-path] quit

# Configure the bypass tunnel: Create MPLS TE tunnel interface Tunnel 5, and specify the tunnel

destination address as LSR ID of Router C, the tunnel signaling protocol as RSVP-TE, and the

explicit path to be used as by-path.

[RouterB] interface tunnel 5 mode mpls-te

[RouterB-Tunnel5] ip address 11.1.1.1 255.255.255.0

[RouterB-Tunnel5] destination 3.3.3.3

[RouterB-Tunnel5] mpls te signaling rsvp-te

[RouterB-Tunnel5] mpls te path preference 1 explicit-path by-path

# Configure the bandwidth that the bypass tunnel can protect.

[RouterB-Tunnel5] mpls te backup bandwidth 10000

[RouterB-Tunnel5] quit

# Bind the bypass tunnel to the protected interface.

[RouterB] interface ethernet 1/2

[RouterB-Ethernet1/2] rsvp fast-reroute bypass-tunnel tunnel 5

[RouterB-Ethernet1/2] quit

# Execute the display interface tunnel command on Router B. You can see that the tunnel interface

Tunnel 5 is up.

6. Configure a static route on Router A to direct the traffic destined for subnet 4.1.1.0/24 to MPLS TE

tunnel 4.
