I am unable to ping NE.TW.RKB.IP1 from an outside network. Other machines which do not have access or routes for NET.WOR.KA.0 respond just fine. How do I get it to respond on both NET.WOR.KA.0 and NE.TW.RKB.0 given all default traffic should go through NET.WOR.KA.1 unless it is in reply to traffic from NE.TW.KB.1 or there is an outage.
You probably want to remove the default route through NE.TW.KB.1 and add routes for the specific networks that you can reach though it. Normally routing is done toward a destination network/address without regard to the route of a packet you might be replying to. As for an 'outage', how do you define/detect the outage? Normally if you want routes to be determined dynamically you would set up a routing protocol with the next-hop routers - or for simple failover the alternative gateway routers might be configured via hsrp or vrrp to have a floating IP address that the rest of the LAN uses as the default gateway address.
