Is it possible using any known protocol to trunk vlans across a DS3 connection between two sites?


Site A                                                         Site B                                                 Internet
company  <------------------------------------> ISP / DR Site <------------------------------->
                        DS3                                                                   upstream to internet

Please keep in mind that the company A is the main network and at the DR site we have a seperate fail over network that is connected over a VPN tunnel that rides on top of the DS3.  We want to combine the two networks into one seemless network with our main network VLANS going to the DR site or site B.

VLANs are a layer 2 feature, I suspect that the DS3 will be terminated by routers which are layer 3 devices.

Are you sure you want to pull VLANs over a LAN, bare in mind that they are boradcast domains and so any boradcasts from site A will travel over your expensive DS3, taking up bandwidth.

Perhaps a better option could be to split the sites with a VTP domain at each, both with the same number of VLANs (possibly even with the same names). If you use an ACL on each router you could create it so that only VLANA1 can talk to VLANB1. Depends what you are trying to do.

Hope that helps.
