Suggested Answer: ADE 🗳️
"PIM is IP routing protocol-independent and can leverage whichever unicast routing protocols are used to populate the unicast routing table, including Enhanced
Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), Border Gateway Protocol (BGP), and static routes. PIM uses this unicast routing information to perform the multicast forwarding function. Although PIM is called a multicast routing protocol, it actually uses the unicast routing table to perform the
RPF check function instead of building up a completely independent multicast routing table. Unlike other routing protocols, PIM does not send and receive routing updates between routers." http://www.cisco.com/en/US/docs/ios/solutions_docs/ip_multicast/White_papers/mcst_ovr.html#w p1009068
"Hot Standby Router Protocol (HSRP) is a Cisco proprietary redundancy protocol for establishing a faulttolerant default gateway.
In the configuration procedures, the specified interface must be a Layer 3 interface:" http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/ release/12.2_55_se/configur ation/guide/ swhsrp.html
OSPF (Open Shortest Path First) - routing protocol.
