IPv4 multicast addresses belong to the 224.0.0.0/4 address space. In other words, they range from 224.0.0.0 to 239.255.255.255. Similarly, IPv6 multicast addresses fall in the ff00::/8 address space. The definition of the range of these addresses is a little more complicated than in IPv4...
If multicast addresses of packets are in the ASM group address range, IPv6 PIM-SM uses the ASM model to provide multicast services. MLD snooping & MLD snooping Proxy On an IPv6 network, MLD snooping enables a switch to create and maintain a Layer 2 multicast forwarding table by listening ...
By default, the IPv6 address range of SSM groups is FF3x::/32 (x cannot be 1 or 2). You can configure an SSM group policy to control the SSM group address range for the following purposes: Limiting the SSM group address range to ensure security of multicast networks Expanding the S...
I can configure multiple IPv6 addresses on the interface, if the last 6 hexadecimal characters are similar then there is no need to join another multicast address. For example, let’s configure an IPv6 unicast address: R1(config)#interface FastEthernet 0/0R1(config-if)#ipv6 address 2001:DB...
The solicited-node address facilitates the efficient querying of network nodes during link-layer address resolution, the resolving of a link-layer address of a known IPv6 address. In IPv4, the ARP Request frame is sent to the MAC-level broadcast, disturbing all nodes on the network segment, ...
IPv6 protocol designers tried to solve the problem of every host on the subnet getting involved in ARP processing by using a range of L2+L3 multicast groups. IPv6 address is hashed into a multicast IPv6 address (which is further cached into a multicast MAC address), and the ND queries (...

Complete these tasks to configure IPv6 multicast routing and forwarding: Task Remarks Enabling IPv6 multicast routing Required Configuring IPv6 multicast routing and forwarding Configuring an IPv6 multicast routing policy Optional Configuring an IPv6 multicast forwarding range Optional Configuring ...
The following are the restrictions for configuring IP multicast routing: IP multicast routing is not supported on switches running the LAN Base feature set. Layer 3 IPv6 multicast routing is not supported on the switch. High-availability support for Layer 3 multic...
ip multicast group-range<std-acl>ipv6 multicast group-range<std-acl> If packets appear for any of the groups denied by the ACL, they are dropped in all control protocols, which includes PIM, IGMP, MLD, MSDP, and are also dropped on the data plane. Therefore, no IGMP/MLD cache entries...
