What is an ICMPv6 packet?
ICMPv6 (ICMP for IPv6) ICMPv6 is used by IPv6 nodes to report errors encountered in processing packets, and to perform other internet-layer functions, such as diagnostics (ICMPv6 “ping”).
What is ICMPv6 used for?
ICMPv6 further simplifies the communication process by eliminating obsolete messages. ICMPv6 is a multipurpose protocol and is used for a variety of activities including error reporting in packet processing, diagnostic activities, Neighbor Discovery process and IPv6 multicast membership reporting.
What are two ICMPv6?
Question: What are two ICMPv6 messages that are not present in ICMP for IPv4? (Choose two.) Explanation: ICMPv6 includes four new message types: Router Advertisement, Neighbor Advertisement, Router Solicitation, and Neighbor Solicitation.
What type of message is ICMPv6?
ICMPv6 “type” Numbers
| Type | Name | Reference |
|---|---|---|
| 141 | Inverse Neighbor Discovery Solicitation Message | [RFC3122] |
| 142 | Inverse Neighbor Discovery Advertisement Message | [RFC3122] |
| 143 | Version 2 Multicast Listener Report | [RFC3810] |
| 144 | Home Agent Address Discovery Request Message | [RFC6275] |
Which protocol number represents ICMPv6?
58
ICMPv6, Internet Control Message Protocol for IPv6. IP Protocol: 58.
What 5 message types are used by ICMPv6 to provide addressing?
Internet Control Message Protocol version 6 (ICMPv6) Parameters
- Type 0 – Reserved.
- Type 1 – Destination Unreachable.
- Type 2 – Packet Too Big.
- Type 3 – Time Exceeded.
- Type 4 – Parameter Problem.
- Type 128 – Echo Request.
- Type 129 – Echo Reply.
- Type 130 – Multicast Listener Query.
Do I need ICMP for IPv6?
ICMP is used exclusively with IPv4, and ICMPv6 only exists on IPv6. You can often get away with blocking ICMP outright and not notice anything amiss. However, if you block ICMPv6 entirely, hosts can’t find out about each other so IPv6 stops working altogether.
Which 2 types of ICMP messages are common to both ICMPv4 and ICMPv6?
The ICMP messages common to both ICMPv4 and ICMPv6 include: host confirmation, destination (net, host, protocol, port) or service unreachable, time exceeded, and route redirection.
How does ICMP differ from ICMPv6?
ICMP in IPv6 functions the same as ICMP in IPv4. ICMP for IPv6 generates error messages, such as ICMP destination unreachable messages, and informational messages, such as ICMP echo request and reply messages.
Which two ICMPv6 messages are used during the Ethernet?
The two ICMPv6 messages used in determining the MAC address of a known IPv6 address are the neighbor solicitation and the neighbor advertisement.
What is neighbor solicitation IPv6?
A Neighbor Solicitation (NS) message is sent by a node to determine the link-layer address of a neighbor, or to verify that a neighbor is still reachable via a cached link-layer address. NSes are also used for Duplicate Address Detection (DAD).
