Hello,
I have a general question about DHCP and HSRP.
I have configured two redundant CISCO routers with the IP 10.0.0.2 (active) and 10.0.0.3 (standby).
Their virtual HSRP address is 10.0.0.1 .
When my clients send DHCP pakets to the DHCP-Server over the routers, they send a DHCP-discover to 10.0.0.2 and a discover to 10.0.0.3 but not to 10.0.0.1.
Is this the right way or shouldn´t the pakets go to the HSRP address?
Thanks for your help.

Hi
DHCP Discovers are usually broadcast, not targeted to a specific IP?
If the clients are trying to renew and don't get a response from something they are unicasting to, they'll do a DHCP Discover via broadcast and get picked up by anything on the local subnet that is interested in serving them... so it shouldn't matter.
