Release Information

Statement introduced before JUNOS Release 7.4.

inet-mvpn and inet6-mpvn introduced in JUNOS Release 8.4. Only the signaling option is supported with these statements.

Description

Enable multiprotocol BGP (MP-BGP) by configuring BGP to carry network layer reachability information (NLRI) for address families other than unicast IPv4, to specify MP-BGP 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.
labeled-unicast—Configure the family type to be labeled-unicast. This means that the BGP peers are being used only to carry the unicast routes that are being used by labeled-unicast for resolving the labeled-unicast routes. This statement is supported only with inet and inet6
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.
The remaining statements are explained separately.

Usage Guidelines

See Enabling Multiprotocol BGP.

Required Privilege Level

routing—To view this statement in the configuration.

routing-control—To add this statement to the configuration.
