Interconnecting two core switches

Ethan Banks has a great article @ PACKETattack: in Assembly Required – Interconnecting 2 Ethernet Chassis Switches he describes various options you have when you want to connect your redundant core switches. Using more than one physical link is the obvious choice; most people are careful enough to use at least two linecards, but the true magic begins when you start considering the bandwidth allocation to individual linecards and port groups within linecards.

    Im looking for the best method to connect multiple 3750's over my wireless wan. Currently the Mikrotik's running RouterOS handle all the routing and tunneling but I would like to change this so that the Cisco 3750's handle the routing and tunneling. The reason for this is that I need to create 3 VLANs (Voip, Servers and PC's) and the way the network is currently setup would mean a massive amount of routing would need to be added or changed.

    Any advice will be greatly appreciated.
    Kid Regards,
    Mike
