Hello all,
I've got a very weird issue going on with an ASA where it's only learning one random route from a core switch that it's directly connected to and not anything else, but it's learning the same routes from a different device on the same subnet.
Basically. the switch at 10.10.1.1 has a route directing 10.X.X.X traffic to 10.10.1.2. the switch is also set to redistribute static routes into EIGRP. Other devices that are attached directly to the 10.10.1.1 device are seeing the routes and adding them into their route table. However the ASA at 10.10.1.252 is only learning a very specific route direction specific traffic to a /29 subnet.
On 10.10.1.253, I had to add in the same 10.X.X.X route in order for it to get to the ASA. In the debug logs on the ASA, I can see the ASA getting the route table from the 10.10.1.1 device, and only picking to keep the /29 route, but I'm not sure why.
The ASA is connected only to the .1.1 switch and an ISP.
It's hard to explain the issue since it's such a weird one. I know it's not an ACL issue or a distribution issue because other devices are learning the right routes, and everything is connected on the same subnet. All routes are being learning through the interface that's connected to the switch at 10.10.1.1
Any help is greatly appreciated. Also, the firewall on the 10.10.1 network is actually 10.10.1.254 not 10.10.1.1.
