double discover DHCP message sent by distribution switch

[devmohamedh219]

Hello,

in this topology, configured HSRP + Ip helper-address to DHCP server in distribution switch. 

1- when VPC10 send broadcast DHCP discover will go from access switch1 e1/2 and e1/0 to distribution switch 1 and 2.

2- distribution switch 1,2 will send discover message to DHCP Server

192.168.103.1 => distribution1

192.168.103.2 => distribution2

Should we take care of this problem?

Hi @devmohamedh219 

 This is not a problem actually and the DHCP will reply to the first query
