How to set default gateway

[Hanny Tidore]

Hi Paul,

my server has 3 ethernet cards: 1 for heart beat (eth0) and the other
2 cards (eth1 and eth2) are bonded as bond0. In other words, eth1 and
eth2 are slave to bond0. eth1 and eth2 does not have ip address. Only
bond0 has ip address.

I put the following into ifcfg-bond0 and /etc/sysconfig/network:
         GATEWAY=10.10.10.5

But it seems that the routing is still not right ? 

Thanks.
