The relay servers will be determined based on either Option 61 or per IPIF configured servers. Format config dhcp_relay option_60 state [enable | disable] Parameters enable - Specify to enable the DHCP relay function to use option 60 rules to relay DHCP packets. disable - Specify to disable the DHCP relay function from using option 60 rules to relay DHCP packets.
