  2. Broadcast, unknown-unicast and multicast traffic - Wikipedia

    en.wikipedia.org/wiki/Broadcast,_unknown-unicast...

    In the case of unknown-unicast traffic, a security issue may arise. To prevent flooding unknown-unicast traffic across the switch, it is possible to configure the network equipment to divert unknown-unicast traffic to specific trunk interfaces in order to split broadcast coming from different VLANs or to use specific trunk interfaces for ...

  3. Anycast - Wikipedia

    en.wikipedia.org/wiki/Anycast

    Some anycast deployments on the Internet distinguish between local and global nodes to benefit the local community, by addressing local nodes preferentially. An example is the Domain Name System. Local nodes are often announced with the no-export BGP community to prevent hosts from announcing them to their peers, i.e. the announcement is kept ...

  4. Unicast - Wikipedia

    en.wikipedia.org/wiki/Unicast

    In computer networking, unicast is a one-to-one transmission from one point in the network to another point; that is, one sender and one receiver, each identified by a network address. [ 1 ] Unicast is in contrast to multicast and broadcast which are one-to-many transmissions.

  5. Broadcasting (networking) - Wikipedia

    en.wikipedia.org/wiki/Broadcasting_(networking)

    In computer networking, telecommunication and information theory, broadcasting is a method of transferring a message to all recipients simultaneously. Broadcasting can be performed as a high-level operation in a program, for example, broadcasting in Message Passing Interface, or it may be a low-level networking operation, for example broadcasting on Ethernet.

  6. IPv6 address - Wikipedia

    en.wikipedia.org/wiki/IPv6_address

    A packet sent to an anycast address is delivered to just one of the member interfaces, typically the nearest host, according to the routing protocol's definition of distance. Anycast addresses cannot be identified easily, they have the same format as unicast addresses, and differ only by their presence in the network at multiple points.

  7. Protocol-Independent Multicast - Wikipedia

    en.wikipedia.org/wiki/Protocol-Independent_Multicast

    The protocol is named protocol-independent because it is not dependent on any particular unicast routing protocol for topology discovery, and sparse-mode because it is suitable for groups where a very low percentage of the nodes (and their routers) will subscribe to the multicast session.

  8. Solicited-node multicast address - Wikipedia

    en.wikipedia.org/wiki/Solicited-node_multicast...

    The solicited-node multicast addresses are generated from the host's IPv6 unicast or anycast address, and each interface must have a solicited-node multicast address associated with it. A solicited-node address is created by taking the least-significant 24 bits of a unicast or anycast address and appending them to the prefix ff02::1:ff00:0 / ...

  9. Multicast address - Wikipedia

    en.wikipedia.org/wiki/Multicast_address

    Unicast-prefix-based The 234.0.0.0 / 8 range is assigned as a range of global IPv4 multicast address space provided to each organization that has / 24 or larger globally routed unicast address space allocated; one multicast address is reserved per / 24 of unicast space. [17]
