Hi,
I'm looking at a topology where a number of collapsed PE/P nodes (50>100) access a L2 cloud in a full-mesh topology. The underlying cloud architecture could be something like VPLS from an external provider with the MPLS domain mapped on top. The attached shows the nodes on the periphery of the cloud and these could be spread globally. What I'm looking for are pros and cons and whether there is a case study or CVD for this type of topoolgy. Particular interest is on scalability around IGP, LSP's, sub-optimal routing conditions, IGP/LSP synchronisation, IGP link/domain costs etc... The network will provision L2/L3 VPN's and other standard MPLS features.
Thanks, Wayne
