Configure the BaGPipe driver for BGP VPN¶

The BaGPipe driver is a lightweight implementation of the BGP-based VPNs used as a reference back end for the Neutron BGP VPN Interconnection service.

For the instruction below, we assume that the Neutron BGP VPN Interconnection service is already enabled on the OpenStack controller nodes. To enable BGP VPN, see Enable the BGP VPN Interconnection service.

To configure the BaGPipe driver:

1. Log in to the Salt Master node.

2. Open the cluster.<cluster_name>.openstack.compute.yml file for editing.

3. Add the following parameters:

   parameters:
     ...
     neutron:
       compute:
         bgp_vpn:
           enabled: True
           driver: bagpipe
           bagpipe:
             local_address: <IP address used for BGP peerings>
             peers: <IP addresses of BGP peers>
             autonomous_system: <BGP Autonomous System Number>
             enable_rtc: True # Enable RT Constraint (RFC4684)
         backend:
           extension:
             bagpipe_bgpvpn:
               enabled: True
   

4. Re-apply the Salt configuration:

   salt -C 'I@neutron:compute' state.sls neutron
