MPLS VPN BGP Role


  • BGP well suited to carry the traffic of  hundreds of thousands of routes.
  • It is flexible & extended policies to be implemented.
  • So it is used well in MPLS VPN.
  • In MP BGP 4 address families will be supported.
    • IPv4
    • IPv6
    • VPNv4
    • VPNv6
  • Remaining are unicast, multicast & VRF
  • BGP Extended Community: RT
    • It tells to the PE routers if the route imported into a VRF add at least one RT to that IPv4 route
