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)#
