Quidway S3700 Series Ethernet Switches
Configuration Guide - Multicast
Procedure
Step 1 Configure the IP address of each interface and the unicast routing protocol.
# Configure IP addresses and masks of interfaces on the switches according to
Configure OSPF between switches to ensure that the switches can communicate at the network
layer and update routes through the unicast routing protocol.
For details on how to configure IP addresses of interfaces, see IP Addresses Configuration in
the Quidway S3700 Series Ethernet Switches Configuration Guide - IP Service. For details on
how to configure OSPF, see OSPF Configuration in the Quidway S3700 Series Ethernet Switches
Configuration Guide - IP Routing.
Step 2 Enable multicast on all switches and PIM-SM on all interfaces.
# Enable multicast on all the switches and enable PIM-SM on all interfaces. The configurations
of Switch B, Switch C, and Switch D are similar to the configuration of Switch A, and are not
provided here.
[SwitchA] multicast routing-enable
[SwitchA] interface vlanif 101
[SwitchA-Vlanif101] pim sm
[SwitchA-Vlanif101] quit
[SwitchA] interface vlanif 100
[SwitchA-Vlanif100] pim sm
[SwitchA-Vlanif100] quit
[SwitchA] interface vlanif 200
[SwitchA-Vlanif200] pim sm
[SwitchA-Vlanif200] quit
Step 3 Configure the RP.
This example shows how to configure the static RP and the dynamic RP and to specify the
dynamic RP as the preferred RP and the static RP as the standby RP.
# Configure the dynamic RP on one or more switches in the PIM-SM domain. In this example,
set the service range of the RP and specify the locations of the C-BSR and the C-RP on Switch
E.
[SwitchE] acl number 2008
[SwitchE-acl-basic-2008] rule permit source 225.1.1.0 0.0.0.255
[SwitchE-acl-basic-2008] quit
[SwitchE] pim
# Configure static RPs on all switches. The configurations of Switch B, Switch C, Switch D,
and Switch E are similar to configuration on Switch A, and are not provided here.
[SwitchA] pim
[SwitchA-pim] static-rp 192.168.2.2
Step 4 Configure the range of SSM group addresses.
Issue 01 (2011-10-26)
NOTE
The RP can be configured in two modes: the static RP and the dynamic RP. The static RP can be configured
together with the dynamic RP. You can also configure only the static RP or the dynamic RP. When the
static RP and the dynamic RP are configured simultaneously, you can change the parameter values to
specify which RP is preferred.
NOTE
If you enter preferred to the right of static-rp X.X.X.X, the static RP is selected as the RP in the PIM-SM
domain.
