Parameter
acl-number: Number of basic or advanced ACL. The value ranges from 2000 to 3999.
Description
Use the source-policy command to configure a router to filter the multicast data packet
received according to source (group) address.
Use the undo source-policy command to remove the configuration.
If source address filtering and basic ACL are configured, all the multicast data packets
received will be matched with source addresses. The packet which does not pass the
matching will be discarded.
If source address filtering and advanced ACL are configured, all the multicast data
packets received will be matched with source and group addresses. The packet which
does not pass the matching will be discarded.
This command filters not only multicast data, but also the multicast data encapsulated
in register packet.
If this command is executed repeatedly, the new configuration will overwrite the
previous one.
Example
# Configure to accept the multicast data packets with source address of 10.10.1.2 and
discard the multicast data packets with source address of 10.10.1.1.
