RFC 4390 from 2006: https://tools.ietf.org/html/rfc4390 (Dynamic Host Configuration Protocol (DHCP) over InfiniBand) also stipulates:
As described above, the link-layer address is unavailable to the DHCP server because the link-layer address is larger than the "chaddr" field length. As a result, the server cannot unicast its reply to the client. Therefore, a DHCP client MUST request that the server send a broadcast reply by setting the BROADCAST flag when IPoIB Address Resolution Protocol (ARP) is not possible, i.e., in situations where the client does not know its IP address. [RFC1542] discourages the use of a broadcast reply. But in the case of IPoIB, this is a necessity because the server does not receive the link-layer address. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1529815 Title: InfiniBand DHCP flow with PRA and DHCP relay not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/isc-dhcp/+bug/1529815/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
