I can’t think of any interaction between EIGRP ECLB and the WLC that would 
cause this issue without some other additional factor.  Are you running per 
destination or per packet load balancing?  If it’s per destination, traffic 
back to a controller might be on one link that might be dropping.  Is there 
anything in the logging on the wireless bridges that might indicate that one of 
the links is flapping?  Running per packet has the possibility of causing out 
of order packet delivery.  I’m not familiar enough with the WLC traffic to know 
if that would cause any issues.  Someone else might be able to speak to that?

Subject: [WIRELESS-LAN] EIGRP equal cost load balancing over wireless bridges

Hello all,

Is anyone running two pairs of inexpensive wireless bridges–say ubiquity 
AirFiber–and using EIGRP equal cost load balancing over them? It seems to me 
that should be an inexpensive way to support reasonably high bandwidth building 
over redundant links.

I ask because a while back as a test I changed a remote building with two pairs 
of wireless transparent bridges (one acting as primary / other acting as 
backup, each pair a different vendor but both wired interfaces 100 Mb) from 
routing over the primary to use equal cost load balancing over both. After that 
we'd occasionally see our Cisco capwap APs disassociate and re-associate from 
our WLCs on campus where they weren't doing that when data was routed over a 
single link.

Does anyone know why that might happen with ECLB? Or in any case, is anyone 
successfully using a dual link wireless bridge setup with both links active? 
Thanks
