=> What do you suggest?
The paragraph now reads:
Inbound load balancing - Nodes with replicated interfaces may want
to load balance the reception of incoming packets across
multiple network interfaces on the same link. Such nodes
have multiple link-layer addresses assigned to the same
interface. For example, a single network driver could
represent multiple network interface cards as a single
logical interface having multiple link-layer addresses. Load balancing is handled by allowing routers to omit the
source link-layer address from Router Advertisement packets,
thereby forcing neighbors to use Neighbor Solicitation
messages to learn link-layer addresses of routers. Returned
Neighbor Advertisement messages can then contain link-layer
addresses that differ depending on who issued the
solicitation.Maybe just add a sentence at the start of the second paragraph:
Hosts cannot perform inbound load balancing.
(Another place to put this would be after the first sentence.)
The longer story: because hosts would have to do this with omitting the link-layer address from Neighbor Advertisements, this is not possible because the spec requires that lladdr MUST be included for multicast solicitations, and may be omitted for unicast solicitations; but in the latter case, as the solicitor already knows the address, there is no load balancing to happen (at least in the similar manner)..
