Well, according to RFC 1122, Page 49:
-------------------------------------------------------------------
When there is no route cache entry for the destination host address
(and the destination is not on the connected, the IP layer MUST pick
a gateway from its list of "default" gateways. The IP layer MUST
support multiple default gateways.
-------------------------------------------------------------------

Now mind you, only a few operating systems support this, Solaris being one
of them.  Since Solaris round-robins at the packet level and not the TCP/UDP
stream level, in between the default routes many nasty things can happen.

Now if only VRRP were a reality, we would be much better off. But thanks to
Cisco, I'm afraid VRRP will never see the light of day.
