I have RAS router which has configure relay agent with option 82 (agent.circuit-id). Each user has unique virtual interface, for this reason has each request for IP address unique agent.circuit-id, I see that id in the dhcpd.leases file. Can I give each user static IP address based on the agent.circuit-id? I saw configuration for static IP address based on MAC address. I need configuration for option 82 if is supported.
