[root at redfish root]# 
That first routing entry should not be there and may be a bug. In an 
attempt to solve this problem I added a route on the eth1 interface via 
system settings/network. It didn't help so I removed it but it remains in 
my routing table.
My real default route is the last entry.
Do I need any routing in place for one nic to talk to the other in rh 
land?

Do you have routes to get from where you are to where you want to go?
