Re: [c-nsp] Point to Point T1's and vlan nightmares

It sounds like you should be focusing more on a layer 3 solution than a layer 2 solution - run an IGP between your 3560s or 3750s. Even if you did have proper fiber connectivity between locations, you should be isolating VTP (if _absolutely_ required) to single sites. You should also

Perhaps you could provide layer2 access only via that connection. If you are entirely ethernet based, you could provide VLANs between customers for this private network. A layer3 filtering option would be to only allow access to certain netblocks from this second pipe. If it were done with BGP

Another option would be to get something that does OC3 ports (or bigger) and lets you map out DS1s to subinterfaces. Not sure what Cisco cards would be appropriate. Something like an Adtran opti system, and appropriate cisco card, you could run an OC3/12/48 into your Cisco. I'm sure Adtran
