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
# Create MPLS TE tunnel interface Tunnel 5 for the bypass tunnel.
[RouterB] interface tunnel 5 mode mpls-te
[RouterB-Tunnel5] ip address 11.1.1.1 255.255.255.0
# Specify the tunnel destination address as LSR ID of Router C.
[RouterB-Tunnel5] destination 3.3.3.3
# Specify the tunnel signaling protocol as RSVP-TE.
[RouterB-Tunnel5] mpls te signaling rsvp-te
# Specify the explicit path to be used as by-path.
[RouterB-Tunnel5] mpls te path preference 1 explicit-path by-path
# Set the bandwidth that the bypass tunnel can protect.
[RouterB-Tunnel5] mpls te backup bandwidth un-limited
[RouterB-Tunnel5] quit
# Bind the bypass tunnel to the protected interface.
[RouterB] interface gigabitethernet 2/0/2
[RouterB-GigabitEthernet2/0/2] mpls te fast-reroute bypass-tunnel tunnel 5
[RouterB-GigabitEthernet2/0/2] quit
# Execute the display interface tunnel command on Router B. The output shows that the
tunnel interface Tunnel 5 is up. (Details not shown.)
6. Configure a static route on Router A to direct the traffic destined for subnet 100.1.2.0/24 to
MPLS TE tunnel 4.
[RouterA] ip route-static 100.1.2.0 24 tunnel 4 preference 1
Verifying the configuration
# Execute the display mpls lsp command on each router. The output shows the LSP entries. Router
B and Router C each have two CRLSPs. The bypass tunnel backs up the primary CRLSP.
[RouterA] display mpls lsp
FEC
1.1.1.1/4/48960
2.1.1.2
[RouterB] display mpls lsp
FEC
1.1.1.1/4/48960
Backup
2.2.2.2/5/31857

# Shut down the protected interface GigabitEthernet 2/0/2 on the PLR (Router B).
[RouterB] interface gigabitethernet 2/0/2
[RouterB-GigabitEthernet2/0/2] shutdown
[RouterB-GigabitEthernet2/0/2] quit
