5. 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
# Set the bandwidth that the bypass tunnel can protect.

# Bind the bypass tunnel to the protected interface.

# Execute the display interface tunnel command on Switch B to verify that the tunnel interface
Tunnel 5 is up. (Details not shown.)
6. Configure a static route on Switch A to direct the traffic destined for subnet 100.1.2.0/24 to
MPLS TE tunnel 4.

# Display LSP entries on each switch to verify that Switch B and Switch C each have two CRLSPs
and the bypass tunnel backs up the primary CRLSP.
