A look at Auto-Tunnel Mesh Groups
In this post I would like to give a demonstration of using the Auto-Tunnel Mesh group feature.
As you may know, manual MPLS-TE tunnels are first and foremost unidirectional, meaning that if you do them between two PE nodes, you have to do a tunnel in each direction with the local PE node being the headend.
VRF based path selection
In this post I will be showing you how its possible to use different paths between your PE routers on a per VRF basis.
This is very useful if you have customers you want to “steer” away from your normal traffic flow between PE routers.
Node protection using MPLS-TE Fast ReRoute
In this post i would like to demonstrate the concept of a well known MPLS TE (Traffic Engineering) feature, known as Fast Reroute.
Fast Reroute, as the name implies, is used to create an MPLS network, that has similar convergence properties of SONET/SDH APS of about 50 ms.
