Step 6 Router(config-router)# address-family ipv4 vrf
vrf-name
Enters address family configuration mode and configures the
VRF routing table for BGP routing sessions that use standard
IPv4 address prefixes.
The vrf-name argument specifies the name of the virtual
routing and forwarding (VRF) instance to associate with
subsequent IPv4 address family configuration mode
commands.
Step 7 Router(config-router-af)# redistribute
protocol
Redistributes routes from one routing domain into another
routing domain.
The protocol argument is the source protocol from which
routes are being redistributed. It can be one of the following
keywords: bgp, connected, egp, igrp, isis, ospf, static [ip],
or rip.
The connected keyword refers to routes that are established
automatically by virtue of having enabled IP on an interface.
Step 8 Router(config-router-af)# exit-address-family Exits address family configuration mode.
Step 9 Router(config-router)# address-family vpnv4
[unicast]
Enters address family configuration mode for configuring
BGP routing sessions that use standard Virtual Private
Network (VPN) Version 4 address prefixes.
(Optional) The unicast keyword specifies VPN Version 4
unicast address prefixes.
Step 10 Router(config-router-af)# neighbor {ip-address
| peer-group-name} activate
Activates route exchanges with the global BGP neighbors.
Step 11 Router(config-router-af)# neighbor {ip-address
| peer-group-name} send-community [both]
Specifies that a communities attribute should be sent to a
BGP neighbor.
The both keyword specifies that both communities attributes
should be sent.
