What is dhcpv4RAIFOption?
This read-only integer reports whether the relay is configured to add the Relay Agent Information (RAIF) Option to DHCP packets it forwards. Admins check it to confirm whether option-82-style relay information is being inserted, which many upstream DHCP servers rely on for subnet selection or client authentication. For example, a value of enable(1) confirms the relay is tagging forwarded requests with RAIF option data as described in RFC 3046.
