Which multicast group are joined when IPv6 is enabled?
Notice that because I enabled the IPv6 routing capabilities for this device, one of the multicast groups joined is ALL ROUTERS for the local-link (FF02::2).
How do I join a multicast group?
To join a multicast group, a host sends a join message, using the Internet Group Management Protocol (IGMP), to its first-hop router. Groups are identified by a single class D IP address (in the range 224.0. 0.0 to 239.255. 255.255).
When configuring IPv6 on an interface which two IPv6 multicast groups are joined?
When configuring IPv6 on an interface, which two IPv6 multicast groups are joined? (Choose two.) When an interface is configured with IPv6 address, it automatically joins the all nodes (FF02::1) and solicited-node (FF02::1:FFxx:xxxx) multicast groups.
Does IPv6 support multicast?
Unlike IPv4, there is no broadcast address in IPv6. Instead, IPv6 uses multicast, including an all-IPv6 devices well-known multicast address and a solicited-node multicast address.
What is IPv6 multicast?
IPv6 multicast improves network efficiency by allowing a host to transmit a datagram to a targeted group of receivers. For example, a host may want to send a large video clip to a group of selected recipients. It would be time-consuming for the host to unicast the datagram to each recipient individually.
What does it mean to join a multicast group?
A multicast group is defined by an IP address and a port number. Once a host has group membership, the host will receive any data packets that are sent to that group defined by an IP address/port number.
Which IPv6 address type provides communication between subnets and Cannot route on the Internet?
Which IPv6 address type provides communication between subnets and cannot route on the Internet? A IPv6 Unique Local Address is an IPv6 address in the block FC00::/7. It is the approximate IPv6 counterpart of the IPv4 private address. It is not routable on the global Internet.
What does FE80 mean in IPv6?
Typically, link-local IPv6 addresses have “FE80” as the hexadecimal representation of the first 10 bits of the 128-bit IPv6 address, then the least-significant 64-bits of the address are the Interface Identifier (IID).
Who is ff02 Facebook?
Well-known IPv6 multicast addresses
| ff02::1 | all nodes |
|---|---|
| ff02::1a | all RPL (Routing Protocol for Low-Power and Lossy Networks) routers (used in Internet of Things (IoT) devices) |
| ff02::fb | multicast DNS IPv6 |
| ff02::101 | network time (NTP) |
| ff02::1:2 | all DHCP agents |
What multicast groups must an IPv6 router join?
IPv6 routers must also join the all-routers multicast group FF02:0:0:0:0:0:0:2 (scope is link-local). The solicited-node multicast address is a multicast group that corresponds to an IPv6 unicast or anycast address. IPv6 nodes must join the associated solicited-node multicast group for every unicast and anycast address to which it is assigned.
What is the IPv6 multicast address prefix?
All IPv6 multicast addresses share the prefix of FF00::/8. The first octet is FF ( 1111 1111 ). This way you can tell at a glance if an IPv6 address is intended for multicast or not. and scope ( 1 for node, 2 for link, 5 for site, 8 for organization, and E for global scope). The multicast address ends with the interface ID.
How does a host join a multicast group?
Hosts join multicast groups by sending MLD report messages. The network then delivers data to a potentially unlimited number of receivers, using only one copy of the multicast data on each subnet. IPv6 hosts that wish to receive the traffic are known as group members.
What is a Solicited-Node multicast address?
The solicited-node multicast address is a multicast group that corresponds to an IPv6 unicast or anycast address. IPv6 nodes must join the associated solicited-node multicast group for every unicast and anycast address to which it is assigned.
