4000 Router Series IP Multicast Configuration Guide

2. Enable OSPF on all routers on the PIM-SM network to make sure the network-layer on the PIM-SM

network is interoperable and the routing information among the routers can be dynamically

updated. (Details not shown.)

3. Enable IP multicast routing, IGMP and PIM-SM:

# On Router A, enable IP multicast routing globally, enable IGMP on Ethernet 1/1, and enable

PIM-SM on each interface.

<RouterA> system-view

[RouterA] multicast routing

[RouterA-mrib] quit

[RouterA] interface ethernet 1/1

[RouterA-Ethernet1/1] igmp enable

[RouterA-Ethernet1/1] pim sm

[RouterA-Ethernet1/1] quit

[RouterA] interface ethernet 1/2

[RouterA-Ethernet1/2] pim sm

[RouterA-Ethernet1/2] quit

[RouterA] interface ethernet 1/3

[RouterA-Ethernet1/3] pim sm

[RouterA-Ethernet1/3] quit

# Enable IP multicast routing, IGMP and PIM-SM on Router B and Router C in the same way Router

A is configured. (Details not shown.)

# Enable IP multicast routing and PIM-SM on Router D and Router E in the same way Router A is

configured. (Details not shown.)

4. Configure C-BSRs and C-RPs:

# On Router D, configure the service scope of RP advertisements, configure Ethernet 1/3 as a

C-BSR and a C-RP, and set the hash mask length to 32 and the priority of the C-BSR to 10.

<RouterD> system-view

[RouterD] acl number 2005

[RouterD-acl-basic-2005] rule permit source 225.1.1.0 0.0.0.255

[RouterD-acl-basic-2005] quit

[RouterD] pim

[RouterD-pim] c-bsr 192.168.4.2 hash-length 32 priority 10

[RouterD-pim] c-rp 192.168.4.2 group-policy 2005

[RouterD-pim] quit

# On Router E, configure the service scope of RP advertisements, configure Ethernet 1/3 as a

C-BSR and a C-RP, and set the hash mask length to 32 and the priority of the C-BSR to 20.

<RouterE> system-view

[RouterE] acl number 2005

[RouterE-acl-basic-2005] rule permit source 225.1.1.0 0.0.0.255

[RouterE-acl-basic-2005] quit

[RouterE] pim

[RouterE-pim] c-bsr 192.168.9.2 hash-length 32 priority 20

[RouterE-pim] c-rp 192.168.9.2 group-policy 2005

[RouterE-pim] quit
