Multicast & Broadcast Filters

In addition to the other bridge filters available on the KarlBridge platform, the KarlBridge is able to filter traffic by Ethernet (MAC) Address. This capability is quite powerful and can be used to protect particular network hosts or groups of hosts from traffic originating outside of the local subnet.

In addition to protecting particular hosts, MAC Address filters can also be used filter Ethernet packets by multicast and broadcast address. This allows network administrators to prevent unnecessary multicast and broadcast messages from being propagated throughout the network while allowing other useful messages to get to their proper recipients.

When properly configured, multicast and broadcast filters increase the availability of network bandwidth and help to prevent configuration information from hosts on local subnets from being sent to other subnets or networks. This increases the overall security of the network and contributes to better performance throughout.

For examples of how Multicast and Broadcast Filters can be applied in your network, visit the Solutions section of our Online Library.
