An AS number for the VPN instance IPv4 address family is specified.
During network transfer or service identification, a device needs to be simulated as
multiple BGP devices logically. In this case, you can run the as-number command
to configure an AS number for each VPN instance IPv4 address family.
NOTE
The AS number configured in the BGP-VPN instance IPv4 address family view cannot be the
same as the AS number configured in the BGP view.
5. Run:
peer ipv4-address as-number as-number
The CE is specified as the peer of the VPN.
6. (Optional) When the direct route of the local CE needs to be imported to the VPN
routing table (for being advertised to the remote PE), select either of the following
configurations:
– Run the import-route direct [ med med | route-policy route-policy-name ]*
command to import the direct routes of the local CE to the VPN routing table..
– Run the network ipv4-address [ mask | mask-length ] [ route-policy route-policy-
name ] command to import a specific direct route of the local CE to the VPN routing
table.
NOTE
The PE can automatically learn the direct route to the local CE. The route has a higher priority
than the direct route that is advertised by IBGP. Therefore, if this step is not performed, the PE
does not advertise the direct route to the remote PE using MP-BGP.
Perform the following steps on the CE:
1. Run:
system-view
The system view is displayed.
2. Run:
bgp as-number
The BGP view is displayed.
3. Run:
peer ipv4-address as-number as-number
The PE is specified as the IBGP peer.
4. Run:
import-route { direct | static | rip process-id | ospf process-id | isis
process-id } [ med med | route-policy route-policy-name ]*
The route is imported to the local CE.
The CE advertises its VPN network segment to the connected PE, and the PE then
advertises the address to the remote CE. Note that the type of the imported route may
vary with different networking modes.
Configure the static route between a PE and a CE.
Perform the following steps on the PE. The CE is configured with the static route. The
configurations are common, therefore not mentioned here.
