I`m suddenly having problems with some static routes on a WS-C3750G-12S-E running 12.2(44)SE5.
The routing table is really simple, only some static routes and a couple of VRFs. Gateway of last resort is 10.0.224.29 to network 0.0.0.0 10.0.0.0/16 is variably subnetted, 2 subnets, 2 masks C 10.0.232.0/25 is directly connected, Vlan1801 C 10.0.224.28/30 is directly connected, Vlan1208 S* 0.0.0.0/0 [1/0] via 10.0.224.29
I have several 3750`s running very similar setup in the same network without problems. And this one was working fine till a couple of days ago.
Now clients with addresses in the 10.0.232.0/25 network are routed back to them selves if trying to reach an address in the 10.0.0.0/16 range. That is, if a client with IP 10.0.232.50 tries to reach 10.0.230.50 it loops back to it self. Traceroute shows the 3750 with ip 10.0.232.1 looping it back. If it tries to reach 10.0.230.1 or an IP that is not in use in the 10.0.232.0/25 it routes just fine, and traceroute is fine. For example 10.0.232.43 is not in use, and traceroute from 10.0.232.50 to 10.0.230.43 works just fine. IP 10.0.232.44 is in use, and traceroute from 10.0.232.50 to 10.0.230.44 loops back to 10.0.232.44.
Traceroute to 10.0.230.50 looks like this. 1 10.0.232.1 2 10.0.232.50 3 10.0.232.1 4 10.0.232.50 5 10.0.232.1 6 10.0.232.50 ...
If traceroute or ping is run from the 3750s CLI all is fine, only occurs when running from clients.
This has been working for a long time, no config changes made. Other 3750`s with similar config (same type of subnetting/static routes) work just fine. Hope somebody knows what might cause this, will really appreciate it.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
