Procedure
Step 1 Configure VLANs that the interfaces belong to and assign IP addresses to the VLANIF interfaces
and loopback interfaces according to
The configuration procedure is not mentioned.
Step 2 Configure an IGP protocol on the MPLS backbone network so that PE and P routers can
communicate with each other.
# Configure PE1.
[PE1] ospf
[PE1-ospf-1] area 0
[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] network 12.1.1.0 0.0.0.255
[PE1-ospf-1-area-0.0.0.0] quit
[PE1-ospf-1] quit
# Configure P.
[P] ospf
[P-ospf-1] area 0
[P-ospf-1-area-0.0.0.0] network 2.2.2.9 0.0.0.0
[P-ospf-1-area-0.0.0.0] network 12.1.1.0 0.0.0.255
[P-ospf-1-area-0.0.0.0] network 23.1.1.0 0.0.0.255
[P-ospf-1-area-0.0.0.0] quit
[P-ospf-1] quit
# Configure PE2.
[PE2] ospf
[PE2-ospf-1] area 0
[PE2-ospf-1-area-0.0.0.0] network 3.3.3.9 0.0.0.0
[PE2-ospf-1-area-0.0.0.0] network 23.1.1.0 0.0.0.255
[PE2-ospf-1-area-0.0.0.0] quit
[PE2-ospf-1] quit
After the configuration, OSPF relations are established between PE1, P, and PE2. By running
the display ospf peer command, you can see that the status of the OSPF relations is Full. By
running the display ip routing-table command, you can see that the PEs can learn the routes
of Loopback0 interface of each other.
Take the display on PE1 as an example.
[PE1] display ip routing-table
