In the past I was able to unplug my WAN Connection (T1) and the circuit would failover to the DSL connection through the 1841 routers back to main. Now I am receiving this message:
Reply from 10.210.210.2: TTL Expired in Transit
When I do a tracert the following occurs:
10.210.210.1 and so on.
I have attached the IP routes from both my 3745 Router and my 3750 Core. The 3750 is 10.210.210.1 and the 3745 is 10.210.210.2. It appears that I have a routing loop but I am not sure where. Any advice would be greatly appreciated.
