RE: DHCP backup router

I can never understand the function of default-router.
 
If two default-gws are configured in dhcp server, dhcp server will
always send all of them to the client, say the client is a windows pc.
Windows only takes the first one and use it as default gw.

When the first gw failed, dhcp server won't check the availability of
the default-gw, continues to send all of them to PC and let PC do its
own adjudement. Windows always use the first one regardless it is active
or not.

So I can not see the purpose of setting multiple default-routers.

Suppose we can setup gateway detection ( irdp ) on PC and routers, but
when dhcp is on, irdp won't take precedence.

Just my 2cents.

default-router
To specify the default router list for a Dynamic Host Configuration
Protocol
(DHCP) client, use the default-router DHCP pool configuration command.
To remove the default router list, use the no form of this command.

default-router address [address2...address8]

The IP address of the router should be on the same subnet as the client
subnet. You can specify up to eight routers in the list. Routers are
listed in order of preference (address1 is the most preferred router,
address2 is the next most preferred router, and so on).
