Using Pim Sparse Mode Join Filters - Juniper JUNOSE 11.0.X MULTICAST ROUTING Configuration Manual

JUNOSe 11.0.x Multicast Routing Configuration Guide
Configuration Example
This example uses the configuration shown in Figure 21 on page 216. Two E Series
routers called router Boston and router Chicago are running PIM and are connected
by MPLS tunnels. To configure the routers as PIM remote neighbors:

Using PIM Sparse Mode Join Filters

You can use PIM sparse mode join filters to prevent multicast state from being created
in the PIM sparse mode router. The filters are applied to join entries in PIM join/prune
messages that are received from PIM sparse mode neighbors.
By denying joins at the edge of a network, you can limit the multicast state and traffic
in the network. By accepting only certain joins, you can control which multicast
services an end user can receive. PIM join filters also reduce the potential for denial

Using PIM Sparse Mode Join Filters

host1(config-router-rn)#update-source loopback 5
Use the no version to delete the source address from the connection to the
remote neighbor.
Specify that router Chicago will be a remote neighbor of router Boston, and
identify the IP address on router Chicago that will transmit datagrams to router
Boston.
boston(config-router)#remote-neighbor 1001::1 sparse-mode
Specify the location of the interface that will transmit datagrams from router
Boston to router Chicago.
boston(config-router-rn)#update-source atm 2/1.108
Specify that router Boston will send hello messages to router Chicago every 40
seconds.
boston(config-if)#ipv6 pim query-interval 40
Specify that router Boston will be a remote neighbor of router Chicago, and
identify the IP address on router Boston that will transmit datagrams to router
Chicago.
chicago(config-router)#remote-neighbor 2001::1 sparse-mode
Specify the location of the interface that will transmit datagrams from router
Chicago to router Boston.
chicago(config-router-rn)#update-source atm 2/1.95
Specify that router Chicago will send hello messages to router Boston every 40
seconds.
chicago(config-if)#ipv6 pim query-interval 40
