OK, I thought I had everything figured out with object tracking on a dhcp interface... Well I still have issues. I have cable modem on port Fa4 of the 871 and dsl on a Westell router connected to a switchport off of the 871. Tracking and routing looks good on the console with one small problem. Even though the DHCP learned route is the first route listed (S*) and the DSL static route is listed next (both routes having metric of 254), Internet sites show my public address as the DSL routers side. Another issue is when I unplug the cable modem to simulate a ISP failure, the primary route shifts to the DSL router like a good boy; however, when I plug the cablemodem back up give it a little bit, my router never shifts back to the other route. I know this does not work because when I do an extenede ping from that interface, I get no reply. I have to shut and no shut the interface for this to "work" again. I am thinking this "works" because I am forcing it to a DHCP request again... Any ideas or insight?
I have this problem too.
