Configuring a BGP Session for MPLS VPNs (CLI Procedure)

Note: This section is valid for Layer 2 VPNs and Layer 3 VPNs, but not Layer 2 circuits.

To configure an IBGP session, perform the following steps on each PE router:

1. Configure BGP.

   [edit]user@host# edit protocols bgp group group-name

2. Set the BGP type to internal.

   [edit protocols bgp group group-name]user@host# set type internal

3. Specify the loopback interface.

   [edit protocols bgp group group-name]user@host# set local-address loopback-interface-ip-address

4. Set the Layer 2 or Layer 3 VPN family type to unicast.

   [edit protocols bgp group group-name]user@host# set family family-type unicast
   Replace family-type with l2vpn for a Layer  2 VPN or inet–vpn for a Layer  3 VPN.

5. Enter the loopback address of the neighboring PE router.

   [edit protocols bgp]user@host# set neighbor ip-address

6. Commit the configuration if you are finished configuring the device.

   [edit]user@host# commit
