Two Cisco autonomous APs in bridge mode

Unanswered Question
Oct 2nd, 2010

I'm wondering if anyone has every used two

1242s in bridge mode with both the 2.4 and the 5GHz radios as part of the link.  If so, would you mind sharing?

If not, does anyone have any lab configs they would be willing to share?  This isn't for production - simply labbing it up as some training for students.

I have this problem too.

If your trying to accomplish a Point to Point Bridging soultion it's fairly easy. although you can only do 1 radio at a time (either 2.4Ghz or 5ghz).

I don't presently have a full config I can post here, but I can give  you the biggest pieces of it.
