# Perform the same configurations on Switch B, Switch C, and Switch D as on Switch A. (Details
not shown.)
4. On Switch A, configure the MPLS TE tunnel interface Tunnel 3, specify the tunnel destination
address as the LSR ID of Switch C, configure MPLS TE to use RSVP-TE to establish the tunnel, and
enable CRLSP hot backup for the tunnel.
[SwitchA] interface tunnel 3 mode mpls-te
[SwitchA-Tunnel3] ip address 9.1.1.1 24
[SwitchA-Tunnel3] destination 3.3.3.9
[SwitchA-Tunnel3] mpls te signaling rsvp-te
[SwitchA-Tunnel3] mpls te backup hot-standby
[SwitchA-Tunnel3] quit
5. Configure a static route on Switch A to direct the traffic destined for subnet 20.1.1.0/24 to MPLS
TE tunnel 3:
[SwitchA] ip route-static 20.1.1.2 24 tunnel 3 preference 1
Verifying the configuration
