BGP-4 MPLS VPN scenario with integrated traffic

The objective of this application note is to demonstrate the power of N2X (in particular the BGP-4 changes that were made in the 6.10 release) in simulating a high scaled VPN network from the edge to the core.

In the first part of the application note, we will use N2X to set up the control plane, using:

  • OSPF to simulate the core,
  • BGP-4 to simulate the PE routers and CE routes, and
  • LDP to set up the LSPs used for forwarding the VPN traffic.


We will then create IPv4 traffic from the edge to the core, and MPLS labeled IPv4 traffic from the core to the edge.

The second part of the application note will introduce the concept of the "super VRF", which can be using to dramatically improve the scalability of core to edge traffic creation.

The third (and final) part of the application note will introduce the powerful CreateL3BgpMplsVpnTraffic QuickTool, and how it can be used to set up all of the traffic in a highly scaled VPN scenario in merely a few clicks of the mouse.
