If they do you will need to dot1q tunnel them. Cisco has made it easy in that all you have to do in addition to what you do now with a single VLAN is add the switchport dot1q tunnel command to their interface on either side. The VLAN stack takes another 4 bytes so you will need to raise your backbone's MTU to at least 1504 to support your customer running a 1500 MTU. -Matt On Dec 9, 2008, at 7:47 PM, Travis Johnson wrote: > Hi, > > Normally that is what we do... using Cisco ASA firewalls and setting > up VPN tunnels for the customers... however, this particular customer > needs the full 100Mbps between the ports and "transparent" > transport... and they are paying for it... :) > > Travis > Microserv > > Dennis Burgess - LinkTechs wrote: >> >> Just a FYI, I would just create a tunnel between the two sites.
