IPv6 multicast: [41] The low 32 bits an Ethernet address for IPv6 multicast traffic are the low 32 bits of the multicast IPv6 address used. [ 40 ] : §2.3.1 For example, IPv6 multicast traffic using the address ff02::d uses the MAC address 33-33-00-00-00-0D , and traffic to ff05::1:3 goes to the MAC address 33-33-00-01-00-03 .
A solicited-node multicast address is an IPv6 multicast address used by the Neighbor Discovery Protocol to determine the link layer address associated with a given IPv6 address, which is also used to check if an address is already being used by the local-link or not, through a process called DAD (Duplicate Address Detection). The solicited-node ...
Broadcast packets make use of the broadcast MAC address FF:FF:FF:FF:FF:FF. IPv4 multicast packets are delivered using the Ethernet MAC address range 01:00:5E:00:00:00 through 01:00:5E:7F:FF:FF (with an OUI owned by the IANA). This range has 23 bits of available address space. The first octet (01) includes the broadcast/multicast bit.
Sent by multicast routers to determine which multicast addresses are of interest to systems attached to the network(s) they serve to refresh the group membership state for all systems on its network. Group-specific membership queries Used for determining the reception state for a particular multicast address. Group-and-source-specific queries
Multicast is the most common approach, and each VXLAN network identifier (VNI) is mapped to a single multicast group, while each multicast group may map to one or more VNIs. When a VTEP comes alive it uses the Internet Group Management Protocol to join the multicast groups for the VNIs it uses. When a VTEP has to send BUM traffic it will send ...
The Individual Address Block (IAB) is an inactive registry which has been replaced by the MA-S (MAC address block, small), previously named OUI-36, and has no overlaps in addresses with the IAB [6] registry product as of January 1, 2014. The IAB uses an OUI from the MA-L (MAC address block, large) registry, previously called the OUI registry.
The destination MAC address is an STP multicast address. The IEEE 802 standard Bridge Group Address is 01:80:C2:00:00:00 . [ 11 ] However, several proprietary destination MAC addresses for STP exist, like the Cisco proprietary Per-VLAN Spanning Tree address 01:00:0C:CC:CC:CD [ 12 ] or the Extreme Networks address 03:04:08:00:07:00 , and may be ...
Multiple MAC Registration Protocol is a data link layer (layer 2) protocol to register group MAC addresses (i.e. multicast) on multiple switches. It is an MRP application, originally defined in IEEE 802.1ak-2007 and subsequently included in 802.1Q. It replaced the 802.1D-based GMRP.
