Ive got an odd issue with EIGRP. I've got two sites with 3750's configured as distribution switched, each site also has a 3845 with a DS3 connecting them.
X.X.10.0/24 is configured on the site B distribution switch and show up correctly in the routing table of all 4 devices.
Everything was working fine until we rebooted switch B. Ever since the reboot, the routes are still on all devices as expected but when end points at site A try to ping X.X.10.40 and X.X.10.31 it times out and a trace route shows the site B router is sending it back to the site A router causing a loop. All other devices in the X.X.10.X/24 subnet are working properly.
When I do a show IP route X.X.10.40 or 10.30 on the site B router it only shows the /24 route pointing to the site B switch but that is not how it is actually routing the traffic. When I add static routes on the site B router to send traffic destined for the two individual hosts to the site B switch, it begins to work again. Any ideas what would cause this and how to fix it?
