A system whose network routing table looks like this (abbreviated): Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0 needs to look like this: Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 10.10.0.0 192.168.0.98 255.255.0.0 UG 0 0 0 eth0 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0 The first table is nicely configured by the files under /etc/sysconfig/. The first table becomes the second when this command is run: route add -net 10.10.0.0/16 gw 192.168.0.98 eth0 The question is, which file(s) need to be configured under /etc/sysconfig/-- and with what-- in order to accomplish what the "route add ..." command does?
