3) Configure MPLS TE basic capabilities, and enable RSVP-TE and CSPF
# Configure Switch A.
[SwitchA] mpls lsr-id 1.1.1.9
[SwitchA] mpls
[SwitchA-mpls] mpls te
[SwitchA-mpls] mpls rsvp-te
[SwitchA-mpls] mpls te cspf
[SwitchA-mpls] quit
[SwitchA] interface vlan-interface 1
[SwitchA-Vlan-interface1] mpls
[SwitchA-Vlan-interface1] mpls te
[SwitchA-Vlan-interface1] mpls rsvp-te
[SwitchA-Vlan-interface1] quit
[SwitchA] interface vlan-interface 4
[SwitchA-Vlan-interface4] mpls
[SwitchA-Vlan-interface4] mpls te
[SwitchA-Vlan-interface4] mpls rsvp-te
[SwitchA-Vlan-interface4] quit
Follow the same steps to configure Switch B, Switch C, and Switch D.
4) Create an MPLS TE tunnel on Switch A.
# Configure the MPLS TE tunnel carried on the primary LSP.
[SwitchA] interface tunnel 1
[SwitchA-Tunnel1] ip address 9.1.1.1 24
[SwitchA-Tunnel1] tunnel-protocol mpls te
[SwitchA-Tunnel1] destination 3.3.3.9
[SwitchA-Tunnel1] mpls te tunnel-id 10
# Enable hot LSP backup.
[SwitchA-Tunnel1] mpls te backup hot-standby
[SwitchA-Tunnel1] mpls te commit
[SwitchA-Tunnel1] quit
Perform the display interface tunnel command on Switch A. You can find that Tunnel1 is up.
