第11题:
Dense mode multicast requires explicit join messages from their members.
Dense mode multicast uses a push model to flood traffic throughout the network and then prunes the unwanted traffic.
Sparse mode multicast uses a pull model to send multicast traffic to where it is requested.
Sparse mode uses reverse path forwarding (RPF) to prune off redundant flows.
The primary use of sparse mode multicast is for test labs and router performance testing.
第12题:
It is used in multihome network scenarios.
It can be used with BGP to mitigate DoS and DDoS.
It does not need to have CEF enabled.
It is enabled via the interface level command ip verify unicast reverse-path.
It cannot be used with classification access lists.
