- C.FF02::5
- B.FF02::9
- D.FF02::6
- Answer & Explanation
- Report
Answer : [A]
Explanation :
Explanation :
| EIGRPv6's multicast address stayed very near the same. In IPv4 it was 224.0.0.10; now it is FF02::A (A=10 in hexadecimal notation). |

What multicast addresses does RIPng use?
- A.FF02::A
- C.FF02::5
- B.FF02::9
- D.FF02::6
- Answer & Explanation
- Report
Answer : [B]
Explanation :
Explanation :
| RIPng uses the multicast IPv6 address of FF02::9. If you remember the multicast addresses for IPv4, the numbers at the end of each IPv6 address are the same. |

What two multicast addresses does OSPFv3 use?
- A.FF02::A
- C.FF02::5
- B.FF02::9
- D.FF02::6
- Answer & Explanation
- Report
Answer : [C, D]
Explanation :
Explanation :
| Adjacencies and next-hop attributes now use link-local addresses, and OSPFv3 still uses multicast traffic to send its updates and acknowledgments with the addresses FF02::5 for OSPF routers and FF02::6 for OSPF designated routers. These are the replacements for 224.0.0.5 and 224.0.0.6, respectively. |

Which of the following is true when describing an anycast address?
- A.Packets addressed to a unicast address are delivered to a single interface.
- B.Packets are delivered to all interfaces identified by the address. This is also called one-tomany addresses.
- C.This address identifies multiple interfaces and the anycast packet is only delivered to one address. This address can also be called one-to-one-of-many.
- D.These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.
- Answer & Explanation
- Report
Answer : [C]
Explanation :
Explanation :
| Anycast addresses identify multiple interfaces, which is the same as multicast; however, the big difference is that the anycast packet is only delivered to one address, the first one it finds defined in the terms of routing distance. This address can also be called one-to-one-of-many. |
