Hi all, Sorry for the semi-off topic question, but so few people do this specific server config I thought if anyone has an answer to this they might be here.
I just rebuilt my lab server last night using Ubuntu server edition 12.04. My design uses a breakout switch to support QinQ so the routers can have VLAN subinterfaces and integrate with physical switches. Dynamips interfaces are tied to VLAN subinterfaces on the server using the Dynamips nio_linux feature. Keep in mind, this all *worked fine* under Ubuntu 11.04. I rebuilt the box for other reasons. No changes to the breakout switch, same Ethernet adapters used, etc. Now, the real switch integration works using untagged frames from the virtual routers, but if I use VLAN subinterfaces on the routers they don't seem to make it through. So it's really the double-tagged frames that seem to be a problem, or frames that are already tagged when they hit the server. Again, this all worked under a previous Ubuntu, so just curious if anyone knows of a difference with 12.04 vs earlier versions that might need tweaking. Thanks. Please feel free to reply off-list to keep the noise down and I will repost a solution I I find one. Thanks!
