I am investigating several design options for our new WAN. I would appreciate your thoughts on these options for this new network:
1) pair of 7206 routers connected to MPLS cloud. The routers connect back to a pair of 6506 switches that support VSS technology using GigE interfaces
2) pair of 6506 switches that interface directly to the MPLS network and to the internal switched Ethernet network
Any merits/drawbacks to either option (besides cost)? Redundancy is a key requirement but so is network management, sustainability, and reduced complexity. Thank you.
