NETGEAR 8800 Chassis Switch CLI Manual determine if certain multicast streams are to be treated specially. Typically, if the switch receives a stream with a destination address which is in the in 'permit' mode, that stream is software flooded and no hardware entry is installed. When adding an IPv6 address into the policy file, a 128-bit host address is recommended. This feature is meant to solve the multicast connectivity problem for unknown destination addresses within system reserved ranges. Specifically this feature was introduced to solve the problem of recognizing a certain stream as control packets. To create a policy file for the snooping flood-list, use the following template: # This is a template for MLD Snooping Flood-list Policy File # Add your group addresses between "Start" and "End" # Do not touch rest of file!!!! entry mldFlood { if match any Start of group addresses nlri ff05::100:1/128; nlri ff05::100:15/128 end of group addresses then { permit; } } entry catch_all { if { } then { deny; } } Note: The switch does not validate any IP address in the policy file used in this command. Therefore, slow-path flooding should be used only for streams which are very infrequent, such as control packets. It should not be used for multicast data packets. This option overrides any default mechanism of hardware forwarding (with respect to MLD or PIM) so it should be used with caution. Slow path flooding occurs within the L2 VLAN only. Use the none option to effectively disable slow path flooding. 1248 | Chapter 27. IPv6 Multicast Commands
