Example: Configuring PIM Sparse Mode Remote Neighbors for IPv6

The following example illustrates how to configure PIM sparse mode remote neighbors for IPv6.

Requirements

This example uses the following software and hardware components:

Overview

This example uses the configuration shown in Figure 21. Two E Series routers called router Boston and router Chicago are running PIM and are connected by MPLS tunnels.

Configuring PIM Sparse Mode Remote Neighbors for IPv6

Step-by-Step Procedure

To configure the routers as PIM remote neighbors:

  1. 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
  2. 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
  3. Specify that router Boston will send hello messages to router Chicago every 40 seconds.
    boston(config-if)#ipv6 pim query-interval 40
  4. 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
  5. 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
  6. Specify that router Chicago will send hello messages to router Boston every 40 seconds.
    chicago(config-if)#ipv6 pim query-interval 40
  7. See update-source.

    Note: You can configure multicast on IPv4 and IPv6 interfaces. For information about configuring PIM on IPv4 interfaces, see Configuring PIM for IPv4 Multicast .
    For information about configuring IP interfaces, see Configuring IP in the JunosE IP, IPv6, and IGP Configuration Guide. For information about configuring IPv6 interfaces, see Configuring IPv6 in the JunosE IP, IPv6, and IGP Configuration Guide.
