Distributed Resilient Network Interconnect (DRNI) virtualizes two physical devices into one system through multichassis link aggregation. You can configure PIM on a DR system attached to multicast receivers or multicast sources to prevent single points of failure from interrupting multicast forwarding.

Prerequisites

The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

This document assumes that you have basic knowledge of DRNI and Layer 3 multicast.

Example: Configuring Layer 3 IPv4 multicast on a DR system attached to multicast sources

Network configuration

As shown in Figure 1:

· OSPF runs on the network.

· VOD streams are sent to receiver hosts in multicast. The receivers of different subnets form stub networks, and a minimum of one receiver host exist on each stub network.

· The entire PIM-SM domain contains only one BSR.

· Device C is a Layer 2 device attached to the multicast source. Switch A and Switch B are virtualized into a DR system, which is connected to Switch C through a multichassis aggregate link. VLAN-interface 20 interfaces on the DR system are the gateway for the multicast source.

· Host A is a multicast data receiver attached to Device D.

· The GigabitEthernet 1/0/3 interfaces on Device A and Device B are excluded from the shutdown action by DRNI MAD to set up the keepalive link.

· A VRRP group is configured on VLAN-interface 20 interfaces. In the VRRP group, Device A is the master.

· DR interfaces on Switch A and Switch B permit packets from VLAN 20 to pass through. PIM is enabled on VLAN-interface 20 of Switch A and Switch B.

· IP multicast routing is enabled on Switch A and Switch B.

Network configuration

As shown in Figure 2:

· OSPFv3 runs on the network.

· VOD streams are sent to receiver hosts in multicast. The receivers of different subnets form stub networks, and a minimum of one receiver host exist on each stub network.

· The entire IPv6 PIM-SM domain contains only one BSR.

· Host A is a multicast data receiver attached to Device D.

· The GigabitEthernet 1/0/3 interfaces on Device A and Device B are excluded from the shutdown action by DRNI MAD to set up the keepalive link.

· A VRRP group is configured on VLAN-interface 20 interfaces. In the VRRP group, Device A is the master.

· DR interfaces on Switch A and Switch B permit packets from VLAN 20 to pass through. PIM is enabled on VLAN-interface 20 of Switch A and Switch B.

· IPv6 multicast routing is enabled on Switch A and Switch B.
