Yes, because the nexthop is a v6 nexthop, so things are easy. ;-) > V4-via-v6 aims at solving the problem of forwarding an IPv4 packet to > a next hop with no IPv4 address.

A host that 'usually' only does v4-w-v6 nexthop and does _not_ have a(ny) v4 addresses getting routes with a v4 nexthop that are on a link on which the host also is (but only has a v6 address on). This occurs, for example, if you have an RFC8950 session to a route- server at an IX and the route-server also sends you v4 routes with a _v4_ nexthop. With best regards, Tobias -- Dr.-Ing.
