Example

Networking requirement

As shown in Figure 165, there is a network consisting of four 3Com router
routers, among which Router B and Router C are connected via SDH, and Router
B, Router A and Router D are interconnected via Ethernet.

The four routers all support MPLS, and LSP can be established between any two
routers with the routing protocol OSPF.

Configuration procedure

1 Configuration on Router A:

a Configure LSR ID and enable MPLS and LDP.

[3Com]mpls lsr-id 168.1.1.1

[3Com]mpls

[3Com]mpls ldp

b Configure IP address and enable LDP for Ethernet interface.

[3Com]interface ethernet 8/0/0

[3Com-Ethernet8/0/0]ip address 168.1.1.1 255.255.0.0

[3Com-Ethernet8/0/0]mpls ldp enable

c Enable OSPF on the interfaces connecting Router A and Router B

[3Com]route id 168.1.1.1

[3Com]ospf

[3Com-ospf]area 0

[3Com-ospf-area-0.0.0.0]network 168.1.0.0 0.0.255.255

2 Configuration on Router B:

a Configure LSR ID and enable MPLS and LDP.
