Ian,
Not to get too picky; but since you seem to equate default route and gw of last
resort....
:^)
Oversimplified:
Default route: direction to send traffic when the target is not "contained"
within existing route table entries; usually to a specific gw (just out say
"eth0" requires proxy ARP). Actually, it is contained within 0.0.0.0/0.0.0.0
Default network: "A router that is generating the default for a network also
may need a default of its own. One way of doing this is to specify a static
route to the network 0.0.0.0 through the appropriate router."**
Gateway of last resort: not available to RIPv1 (only one choice -- 0.0.0.0).
With more complex routing protocols, "there might be several networks that can
be candidates for the system default. The router uses both administrative
distance and metric information to determine the default route (gateway of last
resort)."** As in: several default routes, one of which is "last resort".
