I'm currently working on a Design for a MPLS VPN with very fast convergence times.
We have the goal to reach a maximum convergence time of 1,5 seconds when a singel error occurs.
In the Backbone I try to work with FRR (FastReRoute). Between PE and CE I'm not sure what protocol to use. I'm also thinking about L3VPN or L2VPN solution.
Are there any informations, whitepapers, designs about sutch a solution in the web?
Do somebody have experience with sutch convergence times in a MPLS environment?
Thanks and best regrads,
