Introduction

This document introduces BIDIR-PIM configuration examples.

Prerequisites

This document is not restricted to specific software or hardware versions.

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 BIDIR-PIM.

Example: Configuring BIDIR-PIM

Network configuration

As shown in Figure 1:

·     Switch A, Switch B, and Switch C run OSPF.

·     Source 1 and Source 2 send multicast data to multicast group 225.1.1.1.

·     Host A and Host B are member hosts of multicast group 225.1.1.1.

Configure BIDIR-PIM on the switches to implement multicast forwarding.

Table 1 Interface and IP address assignment

Device	Interface	IP address	Device	Interface	IP address
Switch A	Vlan-int100	10.10.1.1/24	Switch C	Vlan-int102	10.102.1.1/24
Switch A	Vlan-int12	10.12.1.1/24	Switch C	Vlan-int13	10.13.1.3/24
Switch A	Vlan-int13	10.13.1.1/24	Switch C	Vlan-int23	10.23.1.3/24
Switch B	Vlan-int101	10.101.1.1/24	Switch C	Vlan-int33	10.33.1.3/24
Switch B	Vlan-int12	10.12.1.2/24	Source 1	—	10.10.1.2/24
Switch B	Vlan-int23	10.23.1.2/24	Source 2	—	10.33.1.4/24

 

Analysis

To meet the network requirements, perform the following tasks:

·     To establish the bidirectional RPT, configure VLAN-interface 12 on Switch A as a C-RP.

·     To use the BSR mechanism to dynamically elect the RP, configure VLAN-interface 12 on Switch A as a C-BSR.

·     To avoid multicast forwarding interruption when the RP fails, specify the unused IP address 10.13.1.4/24 as the static RP. In this way, the link on the subnet 10.13.1.0/24 becomes the RPL. Switch A and Switch C on the link function as the RPs.

Restrictions and guidelines

When you configure BIDIR-PIM, follow these restrictions and guidelines:

·     Enable the same PIM mode on the interfaces that belong to the same VPN instance on each switch.

·     Configure the same static RP on all the switches in the BIDIR-PIM domain.

·     Enable PIM-SM for all interfaces on the switches in the BIDIR-PIM domain.

·     Enable IGMP for the interfaces that connect to the stub networks on all the switches in the BIDIR-PIM domain.
