Yes, they are for redundancy. It's up to the host OS to decide how to
use them (place them in the routing table).

Hi Chuck
Thanks for the reply !
Point taken, but why can we configure 8 possible gateways when
configuring DHCP, are they for redundancy use by one host? otherwise
what's their purpose
TIA

Sam,
I don't believe any DHCP server verifies gateway reachability
before handing out addresses. It just blindly hands out all that are
configured. Hosts are expected to run Dead Gateway Detection protocol
(see RFCs 811 and http://www.freesoft.org/CIE/RFC/1122/56.htm portion of
1122).

Hi Group
I understand when a router is configured as DHCP server it can assign a
default router to hosts on its LAN. The router can also assign 7
additional gateways, how are they treated by the hosts.
Are they part of the leased addresses and hence a host would have 1-8
default gateways. Or if DHCP router notices one of the gateways it is
assigning is down it would assign the next one part as part of the next
lease. And in this case what happens to the hosts already assigned with
the failed gateway.
