from the manpage of the route command:

route add default gw mango-gw

              adds a default route (which will be  used  if  no  other  route
              matches).   All  packets  using  this  route  will be gatewayed
              through "mango-gw". The device which will actually be used  for
              that  route depends on how we can reach "mango-gw" - the static
              route to "mango-gw" will have to be set up before.

you can edit the file /etc/defaultrouter (solaris)
but i am not shure if it works also under linux... but the oute command will do also <as rindi mentioned>

Persistent static routes (default gateway) for any linux distribution can be added to /etc/rc.local

Example:

route add -net 10.10.98.0 netmask 255.255.255.0 gw 10.164.234.132 dev eth1
route add -net 10.164.234.96 netmask 255.255.255.252 gw 10.164.234.132 dev eth1
route add -net 10.164.234.112 netmask 255.255.255.240 gw 10.164.234.132 dev eth1

Redhat check /etc/sysconfig/network:

Example

NETWORKING=yes
HOSTNAME="hostname.linux.org"
GATEWAY="10.164.234.1"
GATEWAYDEV="eth0"
FORWARD_IPV4="yes"

If you have iproute2 installed you can also use it, e.g. ip route add gw-addy dev eth0
