%DHCPD-4-PING_CONFLICT: DHCP address conflict even with exclude

[Kevin18]

Hello,

I am currently working on a HSRP assignment. The active (R1) and standby (R2) router are DHCP Server. But Only R1 get a DHCP conflict even after an exclude command. I think it has something to do with HSRP but I am not sure.

Only after I use the command "clear ip dhcp conflict *", I can solve this problem. But after I close and open the file again, the conflict still exist. Of course I save the progress.

Thank you

you must split the DHCP pool into two part, 
config each part in one HSRP router, otherwise you will see always conflict.

Hello,

I already split the pool into two part.

R1

R2

The domain-name is the same. Should I change this?

I see same subnet in both pool, you must divide subnet
