Re: Another FR newbie questions

It really makes no difference if you put the broadcast on the map to the hub or the map to the spoke. The point is just do it once per DLCI.

In your frame-maps on the spokes, you don't need a broadcast parameter for
the mapping to hub. You do for the mapping to the other spoke(s).
