source-policy acl-number

Public instance PIM view, VPN instance PIM view

acl-number: Basic or advanced ACL number, in the range of 2000 to 3999.

Use the source-policy command to configure a multicast data filter.

Use the undo source-policy command to remove the configured multicast data 
filter.

By default, no multicast data filter is configured.

Note that:

■

If you specify a basic ACL, the device filters all the received multicast packets 
based on the source address, and discards packets that fail the source address 
match.

■

If you specify an advanced ACL, the device filters all the received multicast 
packets based on the source and group addresses, and discards packets that 
fail the match.

■

If this command is executed repeatedly, the last configuration will take effect.

# In the public instance configure the router to accept multicast packets originated 
from 10.10.1.2 and discard multicast packets originated from 10.10.1.1.
