Any router that has lost assert election will prune its downstream interface and maintain the assert state
for a period of time. When the assert state times out, the assert loser will resume IPv6 multicast
forwarding.
When a router fails to receive subsequent IPv6 multicast data from the IPv6 multicast source S, the router
does not immediately delete the corresponding (S, G) entry. Instead, it maintains the (S, G) entry for a
period of time—namely, the IPv6 multicast source lifetime—before deleting the (S, G) entry.
