Need help with Cisco VLAN bridging....
Has anyone had experience bridging multiple VLANs accross a clear-channel DS3? I have 2 3640's populated with 1 FE and 1 HSSI. They are connected by a DS3. I've tried a couple of different configs, including turning one router into a frame swich and building a PVC for each VLAN, but the bridging didn't seem to work. I've tried running SDE directly between the HSSI ports...and that didn't seem to work. I'm up a against a deadline here, and would greatly appreciate any help you can offer. I've also tried a couple of IRB configs. Thanks in advance, craig Craig Holland Network Engineer Yahoo! Inc. (408)731-3572 Y!Messenger: cholland

You could try ATM LANE, although I'm not an expert on ATM so I can't offer any configs. (ATM has the advantage of being implementable on a 3640 without a CSU/DSU on T3/DS3) -- Ryan O'Connell - <ryan@complicity.co.uk> - http://www.complicity.co.uk I'm not losing my mind, no I'm not changing my lines, I'm just learning new things with the passage of time
How did you do the bridging across the PVCs? That seems like a workable solution. Michael --- Craig Holland <cholland@yahoo-inc.com> wrote:

Craig, Apart from other suggestions, I think you also can do this: 1)Put ip address at both ends of the DS3; 2) Esbalish tunnels for each of your vlan using different loopback interfaces; 3)put the vlans in their respective tunnles using brigde-group; 4) use rate limit based on the soure of loopback interface of the tunnel to control how much each tunnel(vlan) can use the DS3; Not sure wether you want to turn on the IRB, probably not. Of course this is preety urgly using layer 3 to solve layer2 problem, but just off the top of my head.
