address-family

Description: 

For BGP, configures the router to exchange addresses for the specified address family. 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. For the VPLS address family, configures the router to exchange layer 2 NLRI for the VPLS address family for a specified VPLS instance. The no version removes the address family.

For RIP, configures RIP in a specific VRF to exchange IPv4 addresses. The no version removes the address family.

Syntax: 

For BGP:

[ no ] address-family { { ipv4 | ipv6 } [ unicast | multicast | [ unicast ] vrf vrfName ] |
{ vpnv4 | vpnv6 } [ unicast ] | l2vpn [ signaling ] | vpls vplsName } }

For RIP:

[ no ] address-family ipv4 [ unicast ] vrf vrfName

• 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
• signaling—Specifies BGP signaling of L2VPN reachability information; currently, this can be omitted with no adverse effects
• vplsName—Name of a VPLS instance for which you are specifying the VPLS address family; must be issued for each separate VPLS instance
