Cannot ping host on different subnet, very confusing
Okay SO, I've got a 3640 running IOS 11.1(20) managing one subnet, and I've got a 1720 IOS 12.1 managing another. The 3640's subnet is 192.168.10.xxx and the 1720's is 192.168.7.xxx
There is a dsl point to point link router using ip 192.168.10.249. It connects to subnet 172.30.10.xxx The 1720's ip is 192.168.7.1 and the 3640 is 192.168.10.243
My problem is this: The router (and conversly the clients) on the 7.xxx subnet cannot ping the dsl router. They can ping EVERYTHING else on that subnet (10.xxx). Ideally, they should be able to use the dsl link to get to resources on the 172.30.10.xxx subnet. But it's confusing because they can't even ping the dsl router. Any suggestions as to where to look to find a clue, or ideas on things to try would be very much appreciated. My apologies if my posting lacks clarity, but my brain is fuzzy with thinking about this alot.
Re: Cannot ping host on different subnet, very confusing
not sure if I understand your setup correctly. Do you have:
1 DSL router
? How are those routers connected ? Where is the DSL router connected to ? It seems to me that your clients on subnet 192.168.7.0 cannot get to the DSL router because the router has an IP address from the same address space as the 3640. So your clients know how to get to the 3640, but not to the DSL router.
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
