Parameter
acl-number: Number of basic or advanced ACL. The value ranges from 1 to 199.
Description
Using the source-policy command, you can configure a router to filter the
multicast data packet received according to source (group) address. Using the
undo source-policy command, you can 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.
