Using Access Lists For Pim Join Filters - Juniper JUNOSE 11.2.X IP SERVICES Configuration Manual

Using Access Lists for PIM Join Filters

Copyright © 2010, Juniper Networks, Inc.
You can apply access lists to PIM sparse mode interfaces along with the ip pim join-filter
or ipv6 pim join-filter command to use the access lists as PIM sparse mode join filters.
To configure PIM join filters:
Create the various access list services you want to use with the PIM join filter

command.
host1(config)#! create bronze service
host1(config)#! - restrict SSM channels to 232.0.1/24 only
host1(config)#access-list bronze permit ip host any 228.0.0.0 0.0.0.255

host1(config)#
host1(config)#! create silver service

Enable IP multicast routing.
2.
host1(config)#ip multicast-routing
Enable PIM source-specific multicast router.
3.
host1(config)#ip pim ssm
Identify the default PIM join filter.
4.
host1(config)#ip pim join-filter bronze
Enable PIM sparse mode on a subinterface.
5.
host1(config)#interface atm 3/0.101
host1(config-if)#ip address 101.0.0.1 255.255.255.255
host1(config-if)#ip pim sparse-mode
This interface (and any other PIM interface to which you do not specifically assign
an access list filter) uses the default (bronze) join filter.
Enable PIM sparse mode on another subinterface and assign the silver join filter.
