3Com Switch 7750 Series
Command Reference Guide – Multicast Chapter 5 PIM Configuration Commands
5-20
Description
Use the source-policy command to configure the router to filter the received multicast
data packets according to the source address or group address.
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.
