address family-vrf mode.

multicast Address Family modifier
unicast Address Family modifier
VRF vrf VRF-NAME For MPLS-VPN
VRF-NAME A name used to identify a VRF
Command Mode

Usage
Use address-family ipv4 vrf command to configure routing exchange between Provider Edge (PE) and
Customer Edge (CE) devices. The BGP sessions between PE routers can carry different types of routes
(VPN-IPv4, IPv4, VPN-IPv4 and IPv4 routes). Address families are used to control the type of BGP session.
Configure a BGP address family for each VRF configured on the PE router and a separate address family to
carry VPN-IPv4 routes between PE routers. All non VPN BGP neighbors are defined using the Router mode.
All VPN BGP neighbors are defined under its associated Address Family mode. The BGP process with no
address-family specified, is the default address-family where any sessions are configured that either are not
associated with a VRF or are used to carry IPv4 routes.
Examples
The following example places the router in address family configuration mode and specifies vrf1 as the name
of the VRF instance to associate with subsequent IP Version 4 address family configuration mode commands:
Switch(config)# router bgp 100
Switch(config-router)# address-family ipv4 vrf Switch
Switch(config-router-af)#
