 We have 3 controller nodes each running a DHCP agent (so 3 DHCP agents in all).

I am just curious, how much dhcp agents do you have on a network?Is controller monolithic?How much controllers do you have?

Hi folks,
We have a rather large flat network consisting of over 300 ironic baremetal nodesand are constantly having the baremetals timing out during their PXE boot due tothe dhcp agent not able to respond in time.
Looking for inputs on successful DHCP scaling techniques that would help mitigate this.
