7 Resilient groups are a type of next-hop group that is aimed at minimizing
12 the legacy multipath next-hop group, which uses the hash-threshold
15 To select a next hop, hash-threshold algorithm first assigns a range of
16 hashes to each next hop in the group, and then selects the next hop by
17 comparing the SKB hash with the individual ranges. When a next hop is
19 reassignment of parts of hash space from one next hop to another. RFC 2992

31 Note how next hop 2 gave up part of the hash space in favor of next hop 1,
