A host stack that implements the draft recognises the sentinel and, instead of sending an ARP request for it, resolves the link-layer address from its IPv6 neighbour cache - where the default router's MAC address already sits, learned through ordinary Router Advertisements and Neighbour Discovery.
How is that handled if multiple IPv6 default routes exist? For me it looks like all of them must be capable of forwarding the IPv4 package. How is that handled if they also should support legacy ARP for this address? HSRP etc.? -- kind regards Marco Junk-Mail bitte an trashcan@stinkedores.dorfdsl.de
