    1. bgp as-number [ instance instance-name ]

    2. address-family ipv4 [ unicast ]

  • Enter BGP-VPN IPv4 unicast address family view:

    1. bgp as-number [ instance instance-name ]

    2. ip vpn-instance vpn-instance-name

    3. address-family ipv4 [ unicast ]

  • Enter BGP IPv4 multicast address family view:
