[Nfd-dev] Best Route strategy doesn't work over ethernet multicast?

Hi Nick

I thought best-route would eventually switch if the one

best-route v4 has no “memory” beyond a single PIT entry. It’ll use a
secondary path only if the downstream retransmits before PIT entry expires.
In another PIT entry, it still starts from the first nexthop.

best-route v4 does not deal with “numerically least-ordered face”. When two
nexthops have the same cost in FIB, their order is unspecified.

Yours, Junxiao
