Chapter 3 Configuring Remote Access to MPLS VPN
Defining PVCs
To define PVCs, 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 unnumbered
Loopback number
Step 4
Router(config-subif)# pvc [vpi/vci
number]
Step 5
Router(config-subif-pvc)# encapsulation
aal5snap
Step 6
Router(config-subif-pvc)# no protocol ip
inarp
Configuring Label Switching
To configure label switching on the interface connected to the MPLS cloud, enter the following
commands beginning in global configuration mode:
Command
Step 1
Router(config)# interface atm
slot/port.subinterface-number
tag-switching
Step 2
Router(config-subif)# ip address address
Step 3
Router(config-subif)# tag-switching atm
vp-tunnel vpi
Step 4
Router(config-subif)# tag-switching ip
Configuring the VRF for Each VPN
To configure the VRF for each VPN, enter the following commands beginning in global configuration
mode:
Command
Step 1
Router(config)# ip vrf vrf-name
Step 2
Router(config-vrf)# rd
route-distinguisher
Step 3
Router(config-vrf)# route-target {import
| export | both}
route-target-ext-community
OL-2226-23
Purpose
Specifies an ATM point-to-point subinterface. Enters subinterface
configuration mode.
Associates a VRF with the ATM point-to-point subinterface.
Configures the ATM subinterface as unnumbered to a loopback
interface.
The loopback interface must be in the same VRF.
Note
Configures the PVC on the subinterface. Enters PVC
configuration mode.
Configures the ATM adaptation layer (AAL) and encapsulation
type on the ATM PVC.
Disables Inverse ARP on the ATM PVC.
Purpose
Connects to an MPLS cloud using MPLS ATM tagging. Enters
subinterface configuration mode.
Assigns an IP address to the ATM subinterface.
Specifies an interface or subinterface as a virtual private (VP)
tunnel.
Enables label switching of IP packets on the interface.
Purpose
Enters VRF configuration mode and defines the virtual routing
instance by assigning a VRF name.
Creates routing and forwarding tables.
Creates a list of import and export route target communities for
the specified VRF.
