Required 

Associate a tunneling policy 
with the VPN instance 

tnl-policy tunnel-policy-name 

Required 

By default, the LSP tunnel is 
used and the number of tunnels 
for load balancing is 1. 

 

Create the tunneling policy before associating it with the VPN instance. Otherwise, the default policy will 

be used. 

 

This section describes how to configure a simple MPLS L3VPN, where only one carrier is involved, the 

MPLS backbone is not inter-provider, and none of the PEs or CEs functions as a PE and a CE at the 

same time. 

Some special MPLS L3VPN networking scenarios such as HoVPN, multi-role host, and inter-provider 

VPN require additional configurations. For more information, refer to the related sections in this chapter. 

In configuring MPLS L3VPN, the key task is to manage the advertisement of VPN routes on the MPLS 

backbone and includes the management of route advertisement between PEs and CEs and that 

between PEs. 

As for the route exchange between a PE and a CE, you can configure static routes, multiple RIP 

instances, multiple OSPF instances, multiple IS-IS instances, or BGP according to the networking 

situations. MP-IBGP is adopted between PEs. 

Before configuring basic MPLS L3VPN, complete these tasks: 

z 

Configure IGP for the MPLS backbone (PEs and Ps) to achieve IP connectivity 

z 

Configure MPLS basic capability for the MPLS backbone (PEs and Ps) 

z 

Configure MPLS LDP for the MPLS backbone (PEs and Ps) so that LDP LSPs can be established 

z 

On CEs, configure the IP addresses of the interfaces for accessing the PEs 

Follow these steps to configure a VPN instance:
