Huawei quidway s7700 - Configuring Filtering Rules Based on Source Addresses

Step 2 Run:
pim [ vpn-instance vpn-instance-name ]
The PIM view is displayed.
Step 3 Run:
source-lifetime interval
The lifetime of a source is set.
If a switch does not receive any (S, G) packet in the lifetime of the source, the switch considers
that the source stops sending multicast data to G and the (S, G) entry becomes invalid.
When State-Refresh is enabled, the lifetime of the multicast source is prolonged to about the
value of interval.

5.4.3 Configuring Filtering Rules Based on Source Addresses
After ACL rules are configured, a multicast device can filter the received multicast packets based
on source addresses or source/group addresses.
Context
Do as follows on the PIM switch:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
pim [ vpn-instance vpn-instance-name ]
The PIM view is displayed.
Step 3 Run:
source-policy { acl-number | acl-name acl-name }
The filter is configured.
The effect of the filtering is more obvious if the filter is closer to the source.
l If the basic ACL is configured, only the packets with the source addresses that pass the
filtering are forwarded.
l If the advanced ACL is configured, only the packets with the source addresses and group
addresses that pass the filtering are forwarded.
