Configure a bypass tunnel on Switch B (the PLR):
# Configure an explicit path for the bypass tunnel.

[SwitchB] explicit-path by-path

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

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

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

[SwitchB-explicit-path-by-path] quit

# Create MPLS TE tunnel interface Tunnel 5 for the bypass tunnel.

[SwitchB] interface tunnel 5 mode mpls-te

[SwitchB-Tunnel5] ip address 11.1.1.1 255.255.255.0

# Specify the tunnel destination address as LSR ID of Switch C.

[SwitchB-Tunnel5] destination 3.3.3.3

# Specify the tunnel signaling protocol as RSVP-TE.

[SwitchB-Tunnel5] mpls te signaling rsvp-te

# Specify the explicit path to be used as by-path.

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

# Configure the bandwidth that the bypass tunnel can protect.

[SwitchB-Tunnel5] mpls te backup bandwidth un-limited

[SwitchB-Tunnel5] quit

# Bind the bypass tunnel to the protected interface.

[SwitchB] interface vlan-interface 2

[SwitchB-Vlan-interface2] mpls te fast-reroute bypass-tunnel tunnel 5

[SwitchB-Vlan-interface2] quit

# Execute the display interface tunnel command on Switch B to verify that the tunnel interface

Tunnel 5 is up. (Details not shown.)

Configure a static route on Switch A to direct the traffic destined for subnet 4.1.1.0/24 to MPLS

TE tunnel 4.
