278 CHAPTER 7: USING MULTICAST PROTOCOL COMMANDS must be 224.0.0.0, and source address has no mask), then it means only the (*, *, RP) item will be cleared. If in this command, the group-address is any a group address, and source-address is 0 (where group address can have a mask, and source address has no mask), then only the (*, G) item will be cleared. This command clears multicast route entries from PIM routing table, as well as the corresponding route entries and forward entries in the multicast core routing table and MFC. Related commands: reset multicast routing-table, reset multicast forwarding-table and display pim routing-table. Example Clear the route entries with group address 225.5.4.3 from the PIM routing table. reset pim routing-table 225.5.4.3 source-policy Syntax source-policy acl-number undo source-policy View PIM View Parameter acl-number: Basic or advanced ACL, in the range of 2000 to 3999. Description Use the source-policy command to filter the source (and group) address of multicast data packets. Use the undo source-policy command to remove the configuration. If resource address filtering is configured, as well as basic ACLs, then the router filters the resource addresses of all multicast data packets received. Those not matched will be discarded. If resource address filtering is configured, as well as advanced ACLs, then the router filters the resource and group addresses of all multicast data packets received. Those not matched will be discarded. When this feature is configured, the router filters not only multicast data, but the multicast data encapsulated in the registration packets. The new configuration overwrites the old one if you run the command for a second time. Example Set to receive the multicast data packets from source address 10.10.1.2, but discard those from 10.10.1.1. system-view
