MPLS L3VPN networking schemes 

In MPLS L3VPNs, route target attributes are used to control the advertisement and reception of VPN 
routes between sites. They work independently and can be configured with multiple values to 
support flexible VPN access control and implement multiple types of VPN networking schemes. 

Basic VPN networking scheme 

In the simplest case, all users in a VPN form a closed user group. They can forward traffic to each 
other but cannot communicate with any user outside the VPN. 

For the basic VPN networking scheme, you must assign a route target to each VPN for identifying 
the export target attribute and import target attribute of the VPN. Moreover, this route target cannot 
be used by any other VPNs. 

Figure 49 Network diagram for basic VPN networking scheme 

 

 

As shown in 

Figure 49

, the route target for VPN 1 is 100:1, while that for VPN 2 is 200:1. The two 

VPN 1 sites can communicate with each other, and the two VPN 2 sites can communicate with each 
other. However, the VPN 1 sites cannot communicate with the VPN 2 sites. 

Hub and spoke networking scheme 

The hub and spoke networking scheme is suitable for a VPN where all users must communicate with 
each other through an access control device.  

In a hub and spoke network as shown in 

Figure 50

, configure route targets as follows: 

•

 

On spoke PEs (PEs connected to spoke sites), set the export target to Spoke and the import 
target to Hub. 

•

 

On the hub PE (PE connected to the hub site), use two interfaces or subinterfaces that each 
belong to a different VPN instance to connect the hub CE. One VPN instance receives routes 
from spoke PEs and has the import target set to Spoke. The other VPN instance advertises 
routes to spoke PEs and has the export target set to Hub. 

These route targets rules produce the following results: 

•

 

The hub PE can receive all VPN-IPv4 routes from spoke PEs. 

•

 

All spoke PEs can receive VPN-IPv4 routes advertised by the hub PE. 

•

 

The hub PE advertises the routes learned from a spoke PE to the other spoke PEs so the spoke 
sites can communicate with each other through the hub site.
