Procedure
Step 1 Configure the IP addresses of interfaces and the unicast routing protocol on each switch.
# Configure the IP addresses and masks on the interfaces on each switch according to
9-1. IP addresses must be configured on the VLANIF interfaces. OSPF runs between Switch A,
Switch B and Switch C, and the switches can update routes among them through the unicast
routing protocol. The configuration procedure is not provided here.
Step 2 Enable multicast on all switches and PIM-DM on all interfaces.
# Enable multicast on all switches, and PIM-SM on all interfaces. Enable the IGMP function on
the interfaces at the host side. The configurations of other switches are similar to configuration
of Switch B, and are not provided here.
[SwitchB] multicast routing-enable
[SwitchB] interface vlanif 10
[SwitchB-Vlanif10] pim dm
[SwitchB-Vlanif10] quit
[SwitchB] interface vlanif 40
[SwitchB-Vlanif40] pim dm
[SwitchB-Vlanif40] quit
[SwitchB] interface vlanif 50
[SwitchB-Vlanif50] pim dm
[SwitchB-Vlanif50] igmp enable
[SwitchB-Vlanif50] quit
# Run the display multicast rpf-info command on Switch B to view the RPF information of
the source. The RPF routes are unicast routes, and the RPF neighbor is Switch A. The following
information is displayed:
[SwitchB] display multicast rpf-info 8.1.1.2
VPN-Instance: public net
RPF information about source 8.1.1.2:
Step 3 Configure the static multicast route.
# Configure a static multicast RPF route on Switch B, and configure Switch C as the RPF
neighbor.
[SwitchB] ip rpf-route-static 8.1.1.0 255.255.255.0 13.1.1.2
Step 4 Verify the configuration.
# Run the display multicast rpf-info command on Switch B to view the RPF information of
the source. The RPF information is as follows. The RPF routes and the RPF neighbor are updated
according to the static multicast route.
[SwitchB] display multicast rpf-info 8.1.1.2
VPN-Instance: public net
RPF information about source 8.1.1.2:
Issue 01 (2011-10-26)
IP address of the source
Outgoing interface of the route from Switch B to SwitchC: VLANIF 40
NOTE
This configuration example describes only the commands used to configure static multicast routes.
RPF interface: vlanif10, RPF neighbor: 9.1.1.1
Referenced route/mask: 8.1.1.0/24
Referenced route type: unicast
Route selection rule: preference-preferred
Load splitting rule: disable
RPF interface: vlanif40, RPF neighbor: 13.1.1.2
