We've run across a rather odd issue with inter-vlan/bridge-domain routing on a ME-3600X-24FS switch.
When routing to a directly connected subnet from single tagged EVC's we don't see any issues. However, when routing from a double tagged EVC to a single tagged EVC, in different bridge-domain's, same VRF, routing dies. We can successfully PING from a host on the double tagged EVC to an IP on the opposite bridge-domain/vlan configured locally on the 3600X, just not a host connected to the single tagged EVC. We can also successfully PING from a host on the double tagged EVC to a host on the same bridge-domain on a single tagged EVC. So the issue here seems to be from a double tagged EVC to a single tagged EVC, located in a different bridge-domain, same VRF.
From all of our testing this is starting to look like a possible IOS bug. However, we wanted to run this past the community first in case anyone has run into a similar issue or had any suggestions.
