V4-via-v6 uses NDP. Actually, the main difference between ordinary IPv4 next-hop routing and v4-via-v6 is that the latter uses NDP where the former uses ARP. > Technically, there is nothing that keeps a v6 only router doing v4-w-v6 > nh (possibly with RFC8950 behind) from sending a neighbor solicitation > for "who has ::192.0.2.12" when it wants to forward a packet with an > IPv4 next-hop. V4-via-v6 aims at solving the problem of forwarding an IPv4 packet to a next hop with no IPv4 address. In the case you describe above, it looks like the next hop does have an IPv4 address, so apparently you're solving a different problem. Could you please describe the problem you're solving? -- Juliusz _______________________________________________ Int-area mailing list -- int-area@ietf.org To unsubscribe send an email to int-area-le...@ietf.org
