11.2.5 describes MVRP’s use of new, says that when new is received: "any entries in the filtering database for that Port and for the VID corresponding to the attribute value in the MAD_Join primitive are removed.” What is removed? According to 8.8 The Filtering Database, the following entry types may contain information about the relevant port and VID: Dynamic Filtering Entry (Contains: A MAC address, FID, and Port Map for “each outbound Port”) Dynamic VLAN Registration Entry (Contains: A VID, and a Port Map for “each outbound Port”) MAC Address Registration Entry (Contains: A MAC address, VID, and Port Map for “each outbound Port”) Dynamic Reservation Entry (Contains: A VID, a MAC address specification, and a Port Map for “each outbound Port”) Static Filtering Entry (Contains: A MAC address, VID, and Port Map for “each outbound Port”) Static VLAN Registration Entry (Contains: A VID, and a Port Map for “each outbound Port”) =============== Every type of entry contains information about some VID (or FID, in the case of Dynamic Filtering Entries), and every port. One (bad) interpretation of 11.2.5 (which is consistent with 11.2.5) would be, upon receiving a “new” event, to remove all of the listed entries which match the VID which the “new” event was for. This is highly undesirable; in fact, this interpretation puts 11.2.5 in direct conflict with 8.8, because Static Filtering Entries and Static VLAN Registration Entries may only be removed by management The only reasonable thing to discard are Dynamic Filtering Entries. Beyond the type of entry, “removing an entry” (because they contain a port map), effectively unregisters all ports In the case of Dynamic Filtering Entries (8.8.3), this will only deregister it from one port 11.2.5 should more clearly state what information will be removed when a new indication is received.
