what other command? the rt_tables file just associates the names T1 and
Cable with rule #s, it doesn't actually define the rules, for that you
need to use the "ip rule add ..." commands.
me, I make one interface the 'default', and just define ONE extra route
for the 'other' network
say eth0 is 100.100.16.15/24 with a default gateway of 100.100.16.1, and
eth1 is 200.200.18.30/24 with a route of 200.200.18.1 ...
I'd setup the system so the global default gateway is the one on eth0
via /etc/sysconfig/network
then, I'd define ONE extra rule, and one extra route table entry...
ip rule add from 200.200.18.30 table Alt
ip route add default via 200.200.18.1 dev eth1 table Alt
now, these commands are NOT persistent, and, AFAIK, RHEL has no
provision for `ip route` or rule commands, so I end up sticking this
stuff in /etc/rc.d/rc.local or something.
