Advertising the Routes of the PE in the Local AS to the Remote PE

After the routes of the loopback interface on a PE in an AS are advertised to the remote PE in another AS, the MP-EBGP peer relationship is established between the PEs.

Procedure

The loopback address of the PE in the local AS is advertised to the remote ASBR.
Perform the following steps on an ASBR:
1. Access the system view.
```
system-view
```
2. Access the BGP view.
```
bgp { as-number-plain | as-number-dot }
```
3. Advertise the loopback address of the PE in the local AS to the remote ASBR.
```
network ip-address [ mask | mask-length ]
```
4. Return to the system view.
```
quit
```
The BGP routes are imported to IGP.
Perform the following steps on the peer ASBR:
1. Access the system view.
