Abstract
A Multicast Listener Discovery (MLD) protocol query and/or report snooping process is modified to appropriately map secondary PVLAN identifiers to corresponding primary PVLAN identifiers, thereby accommodating other system elements that are otherwise unaware of primary/secondary PVLAN distinctions. Special cases are also accommodated where reverse path forwarding (RPF) checks in support of multicast operation might otherwise fail due to primary/secondary PVLAN distinctions. Additional steps are taken to ensure that PVLAN information properly accounts for changes in configuration and/or location of various network hosts.
