Configuring BGP/MPLS VPN with Static Labels
This section describes the procedures required to configure the system as an MPLS-CE to interact with a PE with static
MPLS label support.
The base configuration, as described in the
Routing
chapter in this guide, must be completed prior to attempt the
configuration procedure described below.
Important:
The feature described in this chapter is a licensed Cisco feature. A separate feature license may be
required. Contact your Cisco account representative for detailed information on specific licensing requirements.
Important:
Commands used in the configuration samples in this section provide base functionality to the extent
that the most common or likely commands and/or keyword options are presented. In many cases, other optional
commands and/or keyword options are available. Refer to the
Command Line Interface Reference
for complete
information regarding all commands.
To configure the system for BGP/MPLS VPN:
Step 1
Create a VRF on the router and assign a VRF name by applying the example configuration in the
Create VRF with
Route-distinguisher and Route-target
section.
Step 2
Set the neighbors and address family to exchange routing information and establish BGP peering with a peer router by
applying the example configuration in the
Set Neighbors and Enable VPNv4 Route Exchange
section.
Step 3
Configure the address family and redistribute the connected routes domains into BGP by applying the example
configuration in the
Configure Address Family and Redistribute Connected Routes
section. This takes any routes from
another protocol and redistributes them to BGP neighbors using the BGP protocol.
Step 4
Configure IP Pools with MPLS labels for input and output by applying the example configuration in the
Configure IP
Pools with MPLS Labels
section.
Step 5
Optional
. Bind DHCP service to work with MPLS labels for input and output in corporate networks by applying the
example configuration in the
Bind DHCP Service for Corporate Servers
section.
Step 6
Optional
. Bind AAA/RADIUS server group in corporate network to work with MPLS labels for input and output by
applying the example configuration in the
Bind AAA Group for Corporate Servers
section.
Step 7
Save your configuration as described in the
System Administration Guide
.
Create VRF with Route-distinguisher and Route-target
Use this example to first create a VRF on the router and assign a VRF name. The second
ip vrf
command creates the
route-distinguisher and route-target.
