Description (partial)

Using a multicast route-map that matches as an SSM Pattern Policy route-map can cause the implicit installed on leafs to get deleted. This can result in mc_fib_miss drops if multicast traffic hits a leaf that doesn't have the specific multicast destination route (example would be transit leaf ftag scenarios). This seems more like a misconfig since SSM should be the group range, not all groups. Raising this enhancement to block this misconfig.
