Using Access Lists for PIM Join Filters

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:

1. 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)#access-list bronze permit ip host 1.1.1.1 232.0.1.0 0.0.0.255

   host1(config)#access-list bronze permit ip host 2.2.2.2 232.0.1.0 0.0.0.255

   host1(config)#

   host1(config)#! create silver service

   host1(config)#! - bronze service + new channels 232.0.2/24

   host1(config)#access-list silver permit ip host any 228.0.0.0 0.0.0.255

   host1(config)#access-list silver permit ip host 1.1.1.1 232.0.1.0 0.0.0.255

   host1(config)#access-list silver permit ip host 2.2.2.2 232.0.1.0 0.0.0.255

   host1(config)#access-list silver permit ip host 1.1.1.1 232.0.2.0 0.0.0.255

   host1(config)#access-list silver permit ip host 2.2.2.2 232.0.2.0 0.0.0.255

   host1(config)#

   host1(config)#! create gold service

   host1(config)#! - silver service + new channels 232.0.3/24

   host1(config)#access-list gold permit ip host any 228.0.0.0 0.0.0.255

   host1(config)#access-list gold permit ip host 1.1.1.1 232.0.1.0 0.0.0.255

   host1(config)#access-list gold permit ip host 2.2.2.2 232.0.1.0 0.0.0.255

   host1(config)#access-list gold permit ip host 1.1.1.1 232.0.2.0 0.0.0.255

   host1(config)#access-list gold permit ip host 2.2.2.2 232.0.2.0 0.0.0.255

   host1(config)#access-list gold permit ip host 1.1.1.1 232.0.3.0 0.0.0.255

   host1(config)#access-list gold permit ip host 2.2.2.2 232.0.3.0 0.0.0.255

2. Enable IP multicast routing.

   host1(config)#ip multicast-routing

3. Enable PIM source-specific multicast router.

   host1(config)#ip pim ssm

4. Identify the default PIM join filter.

   host1(config)#ip pim join-filter bronze

5. Enable PIM sparse mode on a subinterface.

   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.

6. Enable PIM sparse mode on another subinterface and assign the silver join filter.

   host1(config-if)#interface atm 3/0.102

   host1(config-if)#ip address 102.0.0.1 255.255.255.255

   host1(config-if)#ip pim sparse-mode

   host1(config-if)#ip pim join-filter silver

7. Enable PIM sparse mode on another subinterface and assign the gold join filter.

   host1(config-if)#interface atm 3/0.103

   host1(config-if)#ip address 103.0.0.1 255.255.255.255

   host1(config-if)#ip pim sparse-mode

   host1(config-if)#ip pim join-filter gold
