[CentOS] Network routes

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.RKB.1 or there is an outage.

[root at host20 ~]# route -n
