Hello,
Suppose that HSRP is forbidden in this scenario how machines will behave
with the config early provided ?
What is the normal behavior when a router is offering multiple gateways
through DHCP configs ?
I thought of another approach using irdp. Like you keep the DHCP config as
it is without providing default-router through DHCP and the PCs get their
default gateway through irdp.
How about that ?

Unless forbidden in your scenario. Why not consider HSRP as the solution?

Subject: dhcp default-router
Please can anybody confirm my understanding of this one .......
Scenario is simply this. Two routers R1 and R2 on the same ethernet segment.
R1 is handing out dhcp adressess to clients. Under normal circumstances
clients should use R1 as the default router. However if R1 goes down,
clients that already have a valid dhcp lease, should use R2 as the default
router.
Will the config below achieve this :
ip dhcp pool VLANX
default-router R1-IP-Addr R2-IP-Addr (..... up to a max of 8
addresses)
(other dhcp lines removed)
In other words, does the client take the 1st address as its prefered
gateway, followed by the 2nd if the 1st isn't available, and so on until it
finds one which exists?
Thanks,
Chris.
