Which command allows filtering of LSAs in a P2MP network?

The command that allows filtering of Link State Advertisements (LSAs) in a Point-to-Multipoint (P2MP) network is indeed "filter-lsa-out." This command is specifically used in Open Shortest Path First (OSPF) routing protocols to control the outgoing LSAs that are sent from one router to its P2MP neighbors. By applying this command, a network administrator can determine which LSAs should be filtered out based on specific criteria, thus optimizing the routing information distributed across the network.

In P2MP configurations, it becomes essential to manage how LSAs are sent to reduce unnecessary routing updates, minimize bandwidth consumption, and ensure that only relevant and necessary routing information is propagated. Using "filter-lsa-out" contributes to a more efficient P2MP network by allowing selective advertisement of routing information.

The other listed commands either do not exist in the context of OSPF or do not serve the specific function of filtering LSAs in a P2MP network. This command is crucial for maintaining the integrity and performance of routing in diverse and complex network topologies.
