Syntax
config dhcp_relay option_61 state [enable|disable]
Description This decides whether dhcp_relay will process the DHCP option 61 or not.

relay servers cannot be determined based on option 61.
If the relay servers are determined based on option 60 or option 61, then
per IPIF configured servers will be ignored.
If the relay servers are not determined either by option 60 or option 61,
then per IPIF configured servers will be used to determine the relay
servers.

relay server is determined based on option 61, the final relay servers will
be the union of these two sets of the servers.
