hi, we are trying to set up a failover nat. we have a machine with 3 nics - one for local net, eth1 for T1 and eth2 for dsl. what we are trying to acomplish, is when T1 link goes down, the kernel routing table gets updated so that dsl becomes the default gw, and once dsl goes under, T1 takes its place (it its up). ip masquerading and local network are set up and functioning, but the failover mechanism isnt working. another thing i would like to clarify, is: do i have to make any changes to the routing table myself, such as adding default routes by hand, or should bird take care of that completely by it self? we use linux redhat 6.2 on x86 machine, kernel 2.2.19 and the latest version of zebra. thanks so much for any help. max __________________________________________________ Do You Yahoo!?
