Re: DHCP server redundancy

Hi Aashish,

I don't know any features like that...

But just hit upon an idea which uses HSRP.
If you are using two Cisco L3SW or Router as DHCP server...
Then what's happen if you use HSRP between those two, and set ip
helper-address direct to that address?

Regards,

Shogo
