Configuration procedure
1. Configure an IGP on the MPLS backbone to ensure IP connectivity within the backbone:
# Configure PE 1.
<PE1> system-view
[PE1] interface loopback 0
[PE1-LoopBack0] ip address 1.1.1.9 32
[PE1-LoopBack0] quit
[PE1] interface pos 5/1/1
[PE1-POS5/1/1] ip address 172.1.1.1 24
[PE1-POS5/1/1] quit
[PE1] ospf
[PE1-ospf-1] area 0
[PE1-ospf-1-area-0.0.0.0] network 172.1.1.0 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 the P device.
<P> system-view
[P] interface loopback 0
