Description
For BGP, configures the router to exchange addresses
for the specified address family. This command takes effect immediately.
For the IPv4 address family, configures the router or
a specific VRF to exchange IPv4 addresses in unicast, multicast, or
VPN mode.
For the IPv6 address family, configures the router or
a specific VRF to exchange IPv6 addresses in unicast, multicast, or
VPN mode.
For the L2VPN address family, configures a router to exchange
layer 2 NLRI for all VPLS instances and all L2VPN (VPWS) instances.
For the VPLS address family, configures the router to
exchange layer 2 NLRI for the VPLS address family for a specified
VPLS instance.
For the VPWS address family, configures the router to
exchange layer 2 NLRI for the VPWS address family for a specified
L2VPN (VPWS) instance.
For the route-target address family, configures the router
to exchange route-target membership NLRI (RT-MEM-NLRI) that includes
information about membership in VPN route-target extended communities.
For IS-IS, configures IS-IS to exchange IPv6 addresses.
For RIP, configures RIP in a specific VRF to exchange IPv4 addresses.
For all routing protocols, the no version removes the address family.
Options
ipv4—Specifies sessions that carry standard IPv4
address prefixes (default)
ipv6—Specifies sessions that carry IPv6 address
prefixes
multicast—Specifies multicast prefixes
unicast—Specifies unicast prefixes (default)
vrfName—Name of the VRF; string
of 1–32 alphanumeric characters
vpnv4—Specifies sessions that carry customer VPN-IPv4
prefixes, each of which has been made globally unique by adding an
8-byte route distinguisher
vpnv6—Specifies sessions that carry customer VPN-IPv6
prefixes, each of which has been made globally unique by adding an
8-byte route distinguisher
l2vpn—Specifies sessions that carry L2VPN reachability
information
l2vpn signaling—Specifies BGP signaling of L2VPN
reachability information; currently, you can omit the signaling keyword with no adverse effects
route-target—Specifies sessions that carry route-target
membership information
route-target signaling—Specifies BGP signaling of
route-target membership information; currently, this can be omitted
with no adverse effects
vplsName—Name of a VPLS instance
for which you are specifying the L2VPN address family; must be issued
for each separate VPLS instance
vpwsName—Name of a layer 2
VPN (VPWS) instance for which you are specifying the L2VPN address
family; must be issued for each separate L2VPN instance
