It's meant for each of the following cases: router-router router-host host-host I've tried to be careful with using the words "node" and "host". Most stuff applies both to routers and hosts, but there are a few things that only hosts can do because they get to determine the size of packets that are sent, routers have no choice in the matter. I.e., the TCP MSS option makes sure a jumbo-capable host doesn't send TCP segments larger than the standard MTU to a non-jumbo-capable host, and RFC 4821 also only works on hosts. So should implementers want to keep their life simple and omit the neighbor discovery options and jumbo ARP, they can take care of the difference through RFC 4821. But routers can't send larger packets unless this is administratively configured OR the neighbor discovery / jumbo ARP probing takes place. _______________________________________________ Int-area mailing list [email protected] https://www.ietf.org/mailman/listinfo/int-area
