Configuration procedure
1. Configure IP addresses and masks for interfaces according to Figure 35. (Details not shown.)
2. Configure the IGP protocol:
# Enable IS-IS to advertise host routes with LSR IDs as destinations on each node. (Details not
shown.)
# Execute the display ip routing-table command on each switch. You can see that all nodes have
learned the host routes of other nodes with LSR IDs as destinations.
3. Configure basic MPLS TE, and enable RSVP-TE and CSPF:
# Configure Switch A.
<SwitchA> system-view
[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
# Configure Switch B, Switch C, and Switch D in the same way. (Details not shown.)
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
[SwitchA-Tunnel1] mpls te record-route
# Enable hot LSP backup.
[SwitchA-Tunnel1] mpls te backup hot-standby
[SwitchA-Tunnel1] mpls te commit
[SwitchA-Tunnel1] quit
