Abstract
A network device may include a lawful interception module, a routing module, and a multicast distribution table. The lawful interception module may receive a lawful interception request for a subscriber, may inform the routing module about the subscriber, and may provide, to the routing module, a tap interface corresponding to the subscriber. The routing module may receive a multicast join request from the subscriber, and may insert, when the multicast join request is received, the tap interface in the multicast distribution table, as a forwarding interface.
