1. Do Linux implementations of BOOTP/DHCP relay agent use UDP/Datagram Berkely sockets ? 2. On what port DHCP/Bootp server sends unicast BOOTPREPLY/DHCPREPLY UDP replies back to BOOTP/DHCP relay agent ? 3. RFC 1542 says: "Relay agent MUST silently discard any received UDP messages whose UDP destination port number is BOOTPC (68). " - so what the router (where Relay agent is resident) should do with such unicast packets whose UDP destination port number is BOOTPC (68), when they arrive on its interfaces ? Examine if the destination port is matching one of the router's own routing interfaces and drop such, if not matching - route those to the destination ? 4. What (its own) port BOOTP/DHCP relay agent uses to forward to: a) DHCP/Bootp server b) client 5. If BOOTP/DHCP relay agent resides on the router and BOOTPREQUEST/DHCPREQUEST flag indicates that the reply to client should be in BROADCAST mode - should BOOTP/DHCP relay agent/router send BROADCAST reply only on the interface, on which BOOTPREQUEST/DHCPREQUEST was originally received or across all interfaces (except the one on which BOOTREPLY/DHCPREPLY was received from the server) ? ________________________________________________________________ The best thing to hit the Internet in years - Juno SpeedBand!
