Description

Enable multiprotocol BGP (MBGP) by configuring BGP to carry network layer reachability information (NLRI) for address families other than unicast IPv4, to specify MBGP to carry NLRI for the IPv6 address family, or to carry NLRI for VPNs.

Options

any—Configure the family type to be both unicast and multicast.

multicast—Configure the family type to be multicast. This means that the BGP peers are being used only to carry the unicast routes that are being used by multicast for resolving the multicast routes.

unicast—Configure the family type to be unicast. This means that the BGP peers only carry the unicast routes that are being used for unicast forwarding purposes.

Default: unicast

The remaining statements are explained separately in this chapter.
