I have this topology:

OmniTik <-> SXT (wlan1&Ether1 bridged) <-> 751u

Omnitik and 751u configured for OSPF in backbone.

Omnitik 10.0.2.2, additional networks are 10.0.1.0/24
751u 10.0.2.101, additional networks are 10.16.x.0/24, I am adding as the aggregated 10.16.0.0/16

The 751 can see the OmniTik as a neighbor, but the OmniTik cannot see the SXT

just to test, I configure the SXT for OSPF and add network 10.0.2.0/24 which is what the bridge interface has assigned for an IP. The SXT and Omnitik immediatly work!, but neither one sees the 751u as a neighbor.

Now, I add an ipip tunnel between 751u and Omnitik and add 10.77.0.1/24 and 2/24 on each side, add those networks and OSPF comes right up.


Can anyone tell my why OSPF refuses to work across the bridge interface on the SXT? I have another site with the same issue with a 411AH <-> SXT <-> 750gl. exact same issue, I'm sure it is something about the bridge on the SXT.

Thanks for any help.

please export config and paste here

there is not an OSPF config on the SXT. This is only a bridge, but it is somehow getting in the way of OSPF between the devices on either side of the bridge.

might be worth trying station-bridge instead of station-wds

Can station-bridge be used when the ap is in ap-bridge mode?

I thought that OSPF was 100% layer3, so if ip packets are traversing the link, shouldn't OSPF be oblivious to the underlying connection? Granted, it is not behaving in this way for me and the bridge interface does seem to be the culprit.

Try to config the wireless to station-bridge and ospf shuld go up!
