I have the following question, but I don't understand on the answer: When is a dense mode PIM interface added to the mulitcast routing table for a specific group? A) The interface connects a Catalyst switch. Both the router interface and the Catalyst are running CGMP B) The interface is added to the mroute table if DVMRP is heard C) A host has used ICMP to join the group and the router is a designated router D) There are PIM neighbors but the group has been pruned. The answer is B & C. But I thought dense-mode PIM interface is always added to the multicast routing table. Please help.
