You did not say what routing protocols you intend to use. Typically the
IP addresses you specified are typically not routable. They are
designated for private IP spaces. If computers on your LAN with the
172.16.x.x and the 192.168.x.x addresses need access to the internet you
will need NAT. Take a look at the iptables rules for masquerading.
If per chance the addresses were examples and you have real addresses
assigned then zebra is the route demon that replaced routed and gated
