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 (used to be called site-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? OSPFv3

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::/10

What does a unique local unicast range start with? FC00::/7

Describe a global unicast address? These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4.

Describe a unicast address? Packets addressed to a unicast address are delivered to a single interface.

Describe a link-local address? These are like private addresses in IPv4 in that they are not meant to be routed over the Internet.

Describe a unique local address? These addresses are not meant for Internet routing purposes, but they are unique, so it is unlikely they will have an address overlap.

Describe a multicast address? Packets are delivered to all interfaces identified with the address. This is also called a one-to-many address.

Describe an anycast address? This address identifies multiple interfaces and the anycast packet is only delivered to one device. This address can also be called one-to-one-of-many.

Which command enables RIPng? Router1(config-if)#ipv6 router rip 1

Which commands enable EIGRP?

Router1(config)# ipv6 router eigrp 10 Router1(config-rtr)#no shutdown Router1(config-if)#ipv6

A. Global addresses start with 2000::/3. D. There is only one loopback address and it is ::1.

Which of the following statements are true of IPv6 address representation? (Choose two.) A. The first 64 bits represent the dynamically created interface ID. B. A single interface may be assigned multiple IPv6 addresses of any type. C. Every IPv6 interface contains at least one loopback address. D. Leading zeroes in an IPv6 16-bit hexadecimal field are mandatory.

B. A single interface may be assigned multiple IPv6 addresses of any type. C. Every IPv6 interface contains at least one loopback address.

Name threee IPv6 translation mechanisms?

Why IPv6 was not made backward compatible with IPv4? It is an unthinkably HUGE roadblock to adoption!

IPv6’s address space had to be larger than IPv4’s, which meant at the very least longer address fields in the IP header, which would break backwards compatibility anyway.

What is the characteristic of IPV6 unicast addressing?

- Global addresses start from 2000::/3

- There is only one loopback address and it is ::1

Running both IPV4 and IPV6 on a router is called what?

Dual-Stack Routing

What term describes the process of encapsulating IPV6 packets inside IPV4 packets?

-tunneling

What is anycast in IPV6 addressing known as?

one-to-nearest

What command allows IPV6 Forwarding on a router?

IPV6 unicast-routing

Q7) Compare IPV4 to IPV6IPV41) Address are 32 bits(4 bytes)2)Address resource records in the DNS to map host names to IPV4 addresses.3) IPSec is optional and should be supported externally.4) Broadcast addresses are used to send traffic to all nodes on a subnet.5) IPV4 has only stateful configuration.6) Header includes a checksum.7) Header includes option.

Explain various fields in IPV6 base header?

Although IPv6 base header is twice as large as an IPv4 header, it contains less information. Following diagram illustrates the format:

The format of an Ipv6 base header

Most of the space in header is devoted to two fields that identify the sender and recipient.

Each address occupies sixteen octets, four times than an IPv4 address.

In addition to source and destination address, the bas header contains six fields. The VERS field identifies the protocol as version 6. The PRIORITY field specifies the routing priority class. The PAYLOAD LENGTH field corresponds to IPv4's datagram length field. The HOP LIMIT corresponds to the IPv4 TIME-TO-LIVE field. IPv6 interprets the HOP LIMIT strictly. Field FLOW LABEL is intended for use with new applications that requires performance guarantees.
