13.8.4 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 ACL6 rules. The
device then creates PIM entries for only the join information matching ACL6 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 ACL6 rules. The
switch then creates PIM entries for only the join information matching ACL6 rules, which can
prevent illegal users from accessing the group.
Do as follows on the switch enabled with IPv6 PIM-SM:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
Issue 01 (2011-07-15)
hello-option lan-delay interval
The delay of transmitting messages in a LAN is set.
4. Run:
hello-option override-interval interval
The period for overriding the prune action is set.
When a switch receives a Prune message through an upstream interface, it indicates
that another downstream switch exists in the LAN. If the switch still needs to receive
the multicast data, the switch must send a Join message to the upstream within the
override-interval.
