4. Run:
hello-option override-interval interval
The interval for overriding the Prune action is set.
If a switch receives the Prune message through an upstream interface, this indicates
that other downstream switchs exist in this LAN. If the switch still needs to receive
multicast data of the group, the switch must send a Join message to the upstream
switch within the override-interval.

6.9.4 Configuring Join Information Filtering
A Join/Prune message received by an interface may contain both join information and prune
information. You can configure the interface to filter join information based on ACL rules. The
device then creates PIM entries for only the join information matching ACL rules.
Context
A Join/Prune message received by an interface may contain both join information and prune
information. You can configure the switch to filter join information based on ACL rules. The
switch then creates PIM entries for only the join information matching ACL rules, which can
avoid access of illegal users.
Do as follows on the switch enabled with PIM-SM:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
