III. Configuration procedure
1) Configure OSPF as the IGP protocol on the MPLS backbone network.
Configure OSPF on PE1:
[PE1] interface loopback 0
[PE1-LoopBack0] ip address 1.1.1.9 32
[PE1-LoopBack0] quit
[PE1] interface Ethernet1/1/0
[PE1-Ethernet1/1/0] ip address 192.168.1.1 24
[PE1-Ethernet1/1/0] quit
[PE1] ospf
[PE1-ospf-1] area 0
[PE1-ospf-1-area-0.0.0.0] network 192.168.1.0 0.0.0.255
[PE1-ospf-1-area-0.0.0.0] network 1.1.1.9 0.0.0.0
[PE1-ospf-1-area-0.0.0.0] quit
[PE1-ospf-1] quit
Configure OSPF on PE2:
[PE2] interface loopback 0
