HSRP and DHCP

[cer43tcent]

Hello All.  I have HSRP running between two 6500-E switches with a VS-S720-10G.  Vlans on each switch have the ip helper-address x.x.x.x configured.  From running Wireshark on the DHCP server I've noticed that both switches are sending DHCP Informs for a client to the DHCP server.  The DHCP Server is in turn responding back to both switches.  I've read here   https://supportforums.cisco.com/discussion/11056241/dual-dhcp-router-running-hsrp  ; that this is expected.  However, I wonder what others have done in an HSRP environment with a single DHCP server?

There's no harm in having both the active and standby HSRP member router perform the function. The client still only gets one address and, if ever one router is unable to reach the DHCP server (or is itself unreachable) the client continues to get an address without human intervention. I've always set them up just like that with no adverse effect.
