3.3 Routing

Let's talk one more word about routing. When running SLIP or PPP, it's sufficient to have a route add default <remote-ip> somewhere. However, if you want to hook up your machine to a more complex network, it's wise to use routed instead of static routes. Therefore, set routed_flags to "-q" in `/etc/netstart' then, and it will listen for routing-updates.

If you are a gateway yourself (e.g. SLIP/PPP-Ethernet), set routed_flags to "" instead to advertise that route. Also, if there are several gateways on your network, put information about them into `/etc/gateways'.

For example, when DUSK is the SLIP-gateway for NOON (see Picture 1), I set routed_flags to "" and put the following into DUSKs `/etc/gateways':

host    132.199.15.97   gateway 132.199.15.98   metric 1 active

This example establishes a route to NOON (132.199.15.97) via DUSKs SLIP-interface (132.199.15.98). "metric 1" says that NOON is one hop away from DUSK, i.e. that it's directly connected.

Therre's no need to setup a `/etc/gateways' for dial-up SLIP/PPP connections, especially if you're using the combination pppd/chat or bsddip.
