Configure AS number for a
specific neighbor
Delete the AS number of a
specific neighbor
Step 3: Activate peer (group)
By default, BGP neighbor is active while MBGP neighbor is inactive. You should
activate MBGP neighbor in VPNv4 sub-address family view.
Perform the following configuration in VPNv4 sub-address family view to
activate/deactivate peer (group):
Activate the peer (group)
Deactivate the peer (group)
Step 4: Configure MBGP to import VPN route of direct-connect CE
To advertise correct VPN route over public network to other PEs with which BGP
adjacency has been created, a PE must import the VPN routing information of the
direct-connect CE into its MBGP routing table.
For example, if a static route is used between PE and CE, PE must import a static route
in VPN-instance address family sub-view of MBGP (import-route static). If RIP is run
between PE and CE, PE must import an RIP route in VPN-instance view of MBGP
(import-route rip). If BGP is run between PE and CE, MBGP imports a direct-connect
route.
Perform the following configuration in VPN instance address family sub-view to import
IGP route:
Import IGP route
Remove IGP route import
Step 5: Configure BGP as asynchronous.
Perform the following configuration in VPN instance address family sub-view to
configure BGP asynchronous with IGP:
Configure BGP asynchronous with IGP
