eigrp split-horizon on ethernet interfaces NEED HELP

we have a hub and spoke topology, all ethernet WAN over wireless.

4 of the sites are connected via the same antenna hanging off the hub router (2611) (3 spokes, 1 hub)

they are on the same IP WAN subnet

they are on the same IPX WAN network

the spokes are recieving all route updates and saps from the hub router except routes and saps to each other. the hub router knows all. it sounds like a classic split-horizon issue, but the same setup worked fine last week.

although the antenna was repositioned friday.

doing a show ip/ipx eigrp neighbors on the hub router shows all ipx peers

doing a show ip/ipx eigrp neighbors one of the spoke router shows all ipx but it's peers on it's directly "connected" subnet

all is quiet in the log. the routes are not flapping.

has anyone ever had issues with split-horizon over ethernet interfaces?

Re: eigrp split-horizon on ethernet interfaces NEED HELP
