Configuration procedure
1) Configure OSPF, ensuring that PE 1 and PE 2 can learn LSR-ID routes from each other.
# Configure PE 1.
system-view
[PE1] interface loopback 0
[PE1-LoopBack0] ip address 2.2.2.2 255.255.255.255
[PE1-LoopBack0] quit
[PE1] interface vlan-interface 2
[PE1-Vlan-interface2] ip address 10.0.0.1 255.255.255.0
[PE1-Vlan-interface2] quit
[PE1] ospf
[PE1-ospf-1] area 0
[PE1-ospf-1-area-0.0.0.0] network 10.0.0.0 0.0.0.255

# Configure PE 2.

[PE2-ospf-1] quit
After you complete the configuration, the PEs should be able to establish the OSPF neighborship.
Perform the display ospf peer command; you should see that the neighborship state is FULL.
Perform the display ip routing-table command; you should see that the PEs learnt the routes to the
loopback interfaces of each other. Take PE 1 for example:
