| Question | Answer |
|---|---|
| Unicast | Packets addressed to a unicast address are delivered to a single interface. For load balancing, multiple interfaces can use the same address. There are a few different types of unicast addresses, but we don’t need to get into that here |
| Global unicast addresses | These are your typical publicly routable addresses, and they’re the same as they are in IPv4. |
| Link-local addresses | These are like 169.254.1.0 through 169.254.254.255, not meant to be routed. Think of them as a handy tool that gives you the ability to throw a temporary LAN together for meetings or for creating a small LAN that’s not going to be routed |
| Unique local addresses | These addresses are also intended for non-routing purposes, but they are nearly globally unique, so it’s unlikely you’ll ever have one of them overlap. Unique local addresses were designed to replace site-local addresses, so they basically do almost exa |
| Multicast | same as in IPv4, packets addressed to a multicast address are delivered to all interfaces identified by the multicast address. Sometimes people call them one-to-many addresses. It’s really easy to spot a multicast address in IPv6 because they always sta |
| Anycast | Like multicast addresses, an anycast address identifies multiple interfaces, but there’s a big difference: the anycast packet is only delivered to one address—actually, to the first one it finds defined in terms of routing distance. And again, this addr |
| The global unicast address range. | 2000::/3 |
| The unique local unicast range | FC00::/7 |
| The link-local unicast range. | FE80::/10 |
| The multicast range | FF00::/8 |
| Used with 6to4, which is the transition system—the structure that allows IPv6 packets to be transmitted over an IPv4 network without the need to configure explicit tunnels. | 2002::/16 |
| interface ID in an IPv6 address is XXXX bits in length | interface ID in an IPv6 address is 64 bits in length |
| But since the interface ID in an IPv6 address is 64 bits in length and a MAC address is only 48 bits, where do the extra 16 bits come from? | The MAC address is padded in the middle with For example, let’s say I have a device with a MAC address that looks like this: 0060.d673.1987. After it’s been padded, it would look like this: 0260.d6FF.FE73.1987. So where did that 2 in the beginning o |
| padding (called modified eui-64 format) changes a bit to specify if the address is locally unique or globally unique. And the bit that gets changed is the | And the bit that gets changed is the seventh bit in the address. A bit value of 1 means globally unique, and a bit value of 0 means locally unique |
| enable IPv6 on a router, you have to use the | Corp(config)# ipv6 unicast-routing |
| use the eui-64 option | ipv6 address / [eui-64] Corp(config-if)# ipv6 address 2001:db8:3c4d:1::/64 eui-64 |
| You can specify the entire 128-bit global IPv6 address | Corp(config-if)# ipv6 address 2001:db8:3c4d:1:0260.d6FF.FE73.1987/64 |
| how the configuration looks for the stateless DHCP server in the router | Router1(config)# ipv6 dhcp pool test |
| ripng | And it still uses multicast to send its updates too, but in IPv6, it uses FF02::9 for the transport address. This is actually kind of cool since in RIPv2, the multicast address was 224.0.0.9 |
| So in RIPng’s case, if you enable it directly on an interface without going into router configuration mode and starting a RIPng process, a new RIPng process will simply be started for you. It will look something like this: | Router1(config-if)#ipv6 rip 1 enable |
| Which type of packet is addressed and delivered to only a single interface? | Unicast |
| Which type of address is used just like a regular public routable address in IPv4? | Global unicast |
| Which type of address is not meant to be routed? | Link-local |
| Which type of address is not meant to be routed to the Internet but is still globally unique? | Unique local |
| Which type of address is meant to be delivered to multiple interfaces? | Multicast |
| Which type of address identifies multiple interfaces, but packets are delivered only to the first address it finds? | Anycast |
| Which routing protocol uses multicast address FF02::5? | OSPF |
| IPv4 had a loopback address of 127.0.0.1. What is the IPv6 loopback address? | ::1 |
| What does a link-local address always start with? | FE80:: |
| What does a unique local unicast range start with? | FC00::/7 |
| describing a global unicast address? | B. Unlike unicast addresses, global unicast addresses are meant to be routed.These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4. |
| Which of the following is true when describing a unicast address? | A. Explanation:Packets addressed to a unicast address are delivered to a single interface. For load balancing, multiple interfaces can use the same address. A. Packets addressed to a unicast address are delivered to a single interface. |
| Which of the following is true when describing a link-local address? | C. Link-local addresses are meant for throwing together a temporary LAN for meetings or a small LAN that is not going to be routed but needs to share and access files and services locally.These like private addresses in IPv4 they not meant to be routed. |
| Which of the following is true when describing a unique local address? | D. These addresses are meant for nonrouting purposes like link-local, but they are almost globally unique so it is unlikely they will have an address overlap. Unique local addresses were designed as a replacement for site-local addresses. |
| Which of the following is true when describing a multicast address? | B. Packets addressed to a multicast address are delivered to all interfaces IDd by the multicast address, same as in IPv4. It is also called a one-to-many address. You can tell a multicast address in IPv6 cuz multicast addresses always start with FF. |
| Which of the following is true when describing an anycast address? | C. Anycast addresses identify multiple interfaces, same as multicast; but, difference is anycast packet is only sent 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. |
| You want to ping the loopback address of your local host. What will you type? | C. The loopback address with IPv4 is 127.0.0.1. With IPv6, that address is ::1. |
| What two multicast addresses does OSPFv3 use? | C, D. Adjacencies and next-hop attributes now use link-local addresses. OSPFv3 uses multicast traffic to send its updates & ACK w/addresses FF02::5 for OSPF routers, FF02::6 for OSPF DRs. These are replacements for 224.0.0.5 & 224.0.0.6, respectively. |
| What multicast addresses does RIPng use? | FF02::9 |
| What multicast addresses does EIGRPv6 use? | FF02::A |
| To enable RIPng, which of the following would you use? | |
| To enable EIGRP, which three of the following would you use? | |
| To enable OSPFv3, which of the following would you use? | |
