Which protocol number represents ICMPv6?

Which protocol number represents ICMPv6?

58
ICMPv6, Internet Control Message Protocol for IPv6. IP Protocol: 58.

What is ICMPv6?

Internet Control Message Protocol version 6 (ICMPv6) is the implementation of the Internet Control Message Protocol (ICMP) for Internet Protocol version 6 (IPv6). ICMPv6 is an integral part of IPv6 and performs error reporting and diagnostic functions. ICMPv6 has a framework for extensions to implement new features.

What is the difference between ICMP and ICMPv6?

ICMP is available for both IPv4 and IPv6. ICMPv4 is the messaging protocol for IPv4. ICMPv6 provides these same services for IPv6 but includes additional functionality. In this course, the term ICMP will be used when referring to both ICMPv4 and ICMPv6.

What protocol does IPv6 use?

Internet Protocol version 6
IPv6 (Internet Protocol version 6) is a new version of IP protocol designed to solve problems that the previous version (IPv4) encountered by using an address length of 128 bits rather than 32.

What does the ICMPv6 RA message include?

RA messages contain the link-local address and the layer-2 (MAC) address of the first-hop router. Servers can listen to these and use this information to auto-configure their default gateway.

Which of the following is an ICMPv6 informational message?

Echo Request and Echo Reply (used by many commands and utilities like “ping” for network diagnostics and communication trouble shooting) are also ICMPv6 informational messages. The ICMPv6 informational messages have values for the Type field (8 bit binary number) between 128 and 255.

Which two ICMPv6 messages are used during the MAC address resolution process?

ICMPv6 Neighbor Solicitation (NS) and Neighbor Advertisement (NA) messages are used for device-to-device messaging such as address resolution. ICMTPv6 Router Solicitation (RS) and Router Advertisement (RA) messages are used for messaging between devices and routers for router discovery.

What does ICMPv6 mean?

Internet Control Message Protocol version 6 ( ICMPv6) is the implementation of the Internet Control Message Protocol (ICMP) for Internet Protocol version 6 (IPv6). ICMPv6 is defined in RFC 4443.

What is the purpose of the ICMPv6 checksum field?

It is used to create an additional level of message granularity. The checksum field is used to detect data corruption in the ICMPv6 message and parts of the IPv6 header. ICMPv6 messages are grouped into two classes: error messages and informational messages.

Which ICMPv6 error messages must not be originated?

(e) An ICMPv6 error message MUST NOT be originated as a result of receiving the following: (e.1) An ICMPv6 error message. (e.2) An ICMPv6 redirect message [ IPv6-DISC ]. (e.3) A packet destined to an IPv6 multicast address.

What is ICMP (Internet Control Message protocol)?

The ICMP stands for Internet Control Message Protocol. It is a network layer protocol. It is used for error handling in the network layer, and it is primarily used on network devices such as routers.
