Configuring Inter-AS VPN Option A

Configuring Inter-AS VPN Option A

If the MPLS VPN backbone network spans multiple ASs, inter-AS VPN is required. Inter-AS VPN-Option A can be used when each PE device has a few VPNs and VPN routes.


To implement inter-AS VPN Option A, complete basic BGP/MPLS IP VPN configuration in each AS and configure the ASBR-PE devices as the CE device of each other. You need to configure VPN instances for a PE device and an ASBR-PE device respectively. The PE device connects to CE devices, and the ASBR-PE device connects to the remote ASBR-PE device. For details about basic BGP/MPLS IP VPN configuration, see Configuring Basic BGP/MPLS IP VPN Functions.

In inter-AS VPN Option A, the VPN targets of VPN instances on the ASBR and PE devices in the same AS must match for the same VPN. This is not required for the PE devices in different ASs.

Verifying the Configuration

After inter-AS VPN Option A is configured, run the following commands to check previous configurations.

  • Run the display bgp vpnv4 all peer command on the PE or ASBR, and you can view that the status of the BGP VPNv4 peer relationship between the PE and ASBR in the same AS is "Established".

  • Run the display bgp vpnv4 all routing-table command on the PE or ASBR, and you can view the VPNv4 routes.

  • Run the display ip routing-table vpn-instance vpn-instance-name command on the PE or ASBR, and you can view that the VPN routing table of the PE or ASBR has related VPN routes.
