I have the following one nit comment and one question:

  augment "/rt:routing/rt:ribs/rt:rib/"
    + "rt:routes/rt:route/rt:next-hop/rt:next-hop-options/"
    + "rt:next-hop-list/rt:next-hop-list/rt:next-hop"
  {
    description
      "Augment the multiple next hops with repair path.";
    uses repair-path;
  }

The description is slightly misleading. It is to agument a single next-hop in
the next-hop-list, not "multiple next hops".
[Yingzhen] how about: "Augment the next-hop with a repair path."

Zzh> Good.

Shouldn't the repair path be applicable to static routes as well?
[Yingzhen]: Theoretically you can have a repair-path for a static route, but 
have you seen this in deployment?

Zzh> Whether anyone implemented/deployed it that way, I think it’s quite 
reasonable and desired to have it covered in the spec. For example, a static 
route could be using if1 by default but if2 as backup (in case if1 is down).

Zzh> Jeffrey
