I have 2 sites connected via a dedicated 100Mbps line. One site has a 6509 and the other a 4507 (Both layer 3 switches). I could just trunk the vlans accross the two switches but don't want broadcast across that 100Meg connection. So I should route, but routing is less efficient than switching. So I am not sure which direction to go. I am personally leaning toward routing but I have never designed a multisite network and want to know what is best practice in this senario? Thanks for the feedback.
