Unicast IPv4—If you do not explicitly specify the address family, the router is configured
to exchange unicast IPv4 addresses by default. You can also configure the router to
exchange unicast IPv4 routes in a specified VRF.
Multicast IPv4—If you specify the multicast IPv4 address family, you can use BGP to
exchange routing information about how to reach a multicast source instead of a
unicast destination. For information about BGP multicasting commands, see
"Configuring BGP Routing" on page 3. For a general description of multicasting, see
JunosE Multicast Routing Configuration Guide.
VPN IPv4—If you specify the VPN-IPv4 (also known as VPNv4) address family, you
can configure the router to provide IPv4 VPN services over an MPLS backbone. These
VPNs are often referred to as BGP/MPLS VPNs. For detailed information, see
"Configuring BGP-MPLS Applications" on page 383.
Unicast IPv6—If you specify the IPv6 unicast address family, you can configure the
router to exchange unicast IPv6 routes or unicast IPv6 routes in a specified VRF. For a
description of IPv6, see JunosE IP, IPv6, and IGP Configuration Guide.
Multicast IPv6—If you specify the multicast IPv6 address family, you can use BGP to
exchange routing information about how to reach an IPv6 multicast source instead of
an IPv6 unicast destination. For a general description of multicasting, see JunosE
Multicast Routing Configuration Guide.
VPN IPv6—If you specify the VPN-IPv6 address family, you can configure the router to
provide IPv6 VPN services over an MPLS backbone. These VPNs are often referred to
as BGP/MPLS VPNs.
L2VPN—If you specify the L2VPN address family, you can configure the PE router for
VPLS L2VPNs or VPWS L2VPNs to exchange layer 2 network layer reachability
information (NLRI) for all VPLS or VPWS instances. Optionally, you can use the
signaling keyword with the address-family command for the L2VPN address family
to specify BGP signaling of L2VPN reachability information. Currently, you can omit
the signaling keyword with no adverse effects. For a description of VPLS, see
"Configuring VPLS" on page 589. For a description of VPWS, see "Configuring VPWS"
on page 651.
Route-target—If you specify the route-target address family, you can configure the
router to exchange route-target membership information to limit the number of routes
redistributed among members. For a description of route-target filtering, see
"Configuring BGP-MPLS Applications" on page 383.
VPLS—If you specify the VPLS address family, you can configure the router to exchange
layer 2 NLRI for a specified VPLS instance. For a description of VPLS, see "Configuring
VPLS" on page 589.
VPWS—If you specify the VPWS address family, you can configure the PE router to
exchange layer 2 NLRI for a specified VPWS instance. For a description of VPWS, see
"Configuring VPWS" on page 651.
Any command issued outside the context of an address family applies to the unicast
IPv4 address family by default.
