Determine whether the machine being configured will serve as
a router or nonrouter. Set the IPFORWARDING kernel
variable for a router, either with
inconfig(ADMN)
or by using the Network Configuration Manager to
specify that the interface is a gateway.
Determine the routing protocols to be used to communicate
with other machines.
For a nonrouting host, typically use the IRD protocol
and/or the RIP protocol.
For a router, typically use the IRD protocol
and at least one internal routing protocol (RIP or OSPF).
For an exterior router of an autonomous system, also choose
an exterior routing protocol (BGP or EGP).
Select the routing daemon that implements the protocols selected
in the previous step. Use of the IRD protocol requires use of
the IRD daemon (irdd).
Either the routed or gated daemon can be
used for the RIP protocol.
If you need also to use any of the following protocols in conjunction
with RIP (OSPF, EGP, or BGP),
you must use gated to implement RIP.
It is recommended that routed be used only for very simple networks.
Remember that routed and gated cannot both be used;
they are exclusive of each other.
