Re: [Xen-users] Interdomain routing problem



Well, you can do static routers, but you can't do it the way you're trying to do it.  Linux doesn't like to statically route to networks that it can't directly access.  The setup that I gave you is static routing - you assign default gateways to your end servers/clients and static routes on the routers in between.  When the packets get to the routers, the routers know how to deal with them even if the originating host doesn't know exactly where to go.  Unless you get something like the Zebra suite, you can't do dynamic routing in Linux (that I know of).

I want to do it using static routes (for reasons not apparent at this
point)... Am I not doing that in the correct way?



I just realised I should maybe give some more information - this is
all from dom0:
