Configuring basic MPLS L3VPN
The key task in MPLS L3VPN configuration is to manage the advertisement of VPN routes on the
MPLS backbone, including PE-CE route exchange and PE-PE route exchange.
To configure basic MPLS L3VPN:
Task Remarks
Configuring VPN instances
Creating a VPN instance Required.
Associating a VPN instance with
an interface
Required.
Configuring route related attributes
for a VPN instance
Optional.
Configuring a tunneling policy for a
VPN instance
Optional.
Configuring an LDP instance Optional.
Configuring routing between a PE and a CE Required.
Configuring routing between PEs Required.
Configuring routing features for BGP VPNv4 subaddress family Optional.
Configuration prerequisites
Before you configure basic MPLS L3VPN, complete the following tasks:
•
Configure an IGP for the MPLS backbone (on the PEs and Ps) to achieve IP connectivity.
•
Configure basic MPLS for the MPLS backbone.
•
Configure MPLS LDP for the MPLS backbone so that LDP LSPs can be established.
Configuring VPN instances
VPN instances isolate not only VPN routes from public network routes, but also routes among VPNs.
This feature allows VPN instances to be used in network scenarios besides MPLS L3VPNs.
All VPN instance configurations are performed on PEs or MCEs.
Creating a VPN instance
A VPN instance is associated with a site. It is a collection of the VPN membership and routing rules of
its associated site. A VPN instance does not necessarily correspond to one VPN.
The maximum number of VPN instances that can be configured on a PE varies by device.
To create and configure a VPN instance:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Create a VPN instance and
enter VPN instance view.
