OSPF and gated were not designed for casual use. Do find some more
extended description of OSPF, if not the ones I recommended.
To summarize the beginning of chapter 5 of ``Managing IP Networks with
Cisco Routers'', OSPF does not become appropriate until your network
becomes somewhat complex, something past 5 subnets. If you participate
in an organization whose network administrators have chosen OSPF, then
your best source of information will be those network administrators: there
will be all sorts of organization specific aspects of OSPF that you will
have to keep consistent with the rest of the organization, e.g., area
identifiers and bandwidth quantification conventions.
For a simple network, static routing is best. Specifically, if this ppp
connection is your only connection to the larger organization, and you
don't need to advertise multiple networks behind that connection, do not
use OSPF. Use static routing, with the address of the other end of the
ppp connection as the default route. Leave the OSPF headaches to the
network admins on the other end.
Concerning your specific question w.r.t. OSPF and multicast, include in
gated.conf:
define <remote-ppp-ip-address> pointopoint <local-ppp-ip-address> multicast;
and have your ppp startup scripts include
route add -net 240.0.0.0 gw <local-ppp-ip-address> metric 0
I don't believe your suggested use of ifconfig is useful.
