Multi home ignite

[killfast11]

I need to set up a multi homed ignite server.  I have read through the Admin manual,  its states it can be done however, it does not say how.

the system will be on 2 separate networks with 2 separate nics attached, one to each network.  One network is a 172 network the other is a 192 network. 

The system is pingable on both networks,  I have separate DHCP servers so ignite does not have to provide IP's only respond and provide the installs.

Anyone know how to do this? 

Thanks in advance.
