Configuration Tasks for RA to MPLS VPN
Configuring a Dedicated PVC
To configure a dedicated PVC for each VPN, enter the following commands beginning in global
configuration mode:
Command
Step 1
Router(config)# interface atm
slot/port.subinterface-number
point-to-point
Step 2
Router(config-subif)# ip vrf forwarding
vrf-name
Step 3
Router(config-subif)# ip address address
Step 4
Router(config-subif)# pvc [vpi/vci
number]
Step 5
Router(config-subif-pvc)# encapsulation

Configuring BGP to Advertise Networks
To configure BGP to advertise the networks for each VPN, enter the following commands beginning in
global configuration mode:
Command
Step 1
Router(config)# router bgp autonomous-system
Step 2
Router(config-router)# no bgp default
ipv4-unicast
Step 3
Router(config-router)# neighbor {ip-address |
peer-group-name} remote-as as-number
Step 4
Router(config-router)# neighbor {ip-address |
peer-group-name} update-source interface-type
Step 5
Router(config-router)# neighbor {ip-address |
peer-group-name} activate
Step 6
Router(config-router)# address-family ipv4 vrf
vrf-name

Purpose
Creates a point-to-point ATM subinterface. Enters subinterface
configuration mode.
Associates a VRF with the ATM point-to-point subinterface.
Assigns an IP address to the ATM subinterface.
Configures the PVC on the subinterface. Enters PVC
configuration mode.
Configures the ATM adaptation layer (AAL) and encapsulation
type on the ATM PVC.
Purpose
Configures the internal BGP (iBGP) routing process with the
autonomous system number passed along to other iBGP
routers.
Disables IPv4 BGP routing.
Configures the neighboring PE router's IP address or iBGP
peer group and identifies it to the local autonomous system.
The MP-BGP neighbors must use the loopback addresses.
Allows iBGP sessions to use any operational interface for
TCP connections.
Activates route exchanges with the global BGP neighbors.
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.
