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 losers will resume multicast forwarding.
When a router fails to receive subsequent multicast data from 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 multicast source lifetime, before deleting the (S, G) entry.
