CE-to-PE Routing on an MPLS-based IP VPN and ADSL Network

[ayaz.akhtar]

I am in the process of writing a detailed design document for the network shown in the attached diagram.

I am trying to decide which routing protocol to use on this network. At present, my thoughts are as follows:

a) EIGRP for the Data Centre to Core Infrastructure routers.

b) EIGRP for the tunnels and the Branch Office subnets on the ADSL link.

c) Static routing for the CE-to-PE Branch Office connection on the MPLS IP VPN.

d) EIGRP for the CE-to-PE Core Infrastructure connection on the MPLS IP VPN.

There will be approx. 800 Branch Office sites, with the majority connecting over the MPLS IP VPN.

I would appreciate your suggestions on what would be the ‘best’ routing protocol to deploy on this network.

Please provide me with relevant URLs, showing sample configs for the Core Infrastructure and the Branch Office routers connecting over both MPLS IP VPN and ADSL.

Thanks in advance for your help.

MPLS VPNs using EIGRP is a good solution.using Address summarization and redistribution should be made used well. Please refer some of these links for more details;
