I wish I had thought of that. :-) I just noticed that network 10.10.10.0 is reachable via Router 1 and Router 2. I bet Router 1 does not add the 10.10.10.56/29 to its routing table since it can already get to 10.10.10.0/24. Does that make sense?

Re: routing question [7:50434]
Your saying that the machines can only ping the local ethernet interface and not beyond? What if you ping a machine from it's local router sourcing the serial? If that fails you have a default gateway issue or I have seen servers that supposedly support multiple defaults but it doesn't works. Can you ping the remote ethernets from each of the routers??

You are saying that this configuration doesn't work? Nothing seems amiss. Are you sure the interfaces are up and working? Clockrate and all. Are the routes not getting in the routing table?
