Procedure
Step 1 Create VLANs and add interfaces to the VLANs.
Step 2 Configure the IP address of each VLANIF and the unicast routing protocol according to Figure
4-2.
Step 3 Enable IGMP and SSM mapping on the interfaces connected to hosts.
[SwitchD] multicast routing-enable
[SwitchD] interface vlanif 10
[SwitchD-Vlanif10] igmp enable
[SwitchD-Vlanif10] igmp version 3
[SwitchD-Vlanif10] igmp ssm-mapping enable
[SwitchD-Vlanif10] quit
Step 4 Configure the range of SSM group addresses.
# Set the range of SSM group addresses to 232.1.1.0/24 on all Switches. The configurations of
SwitchB, SwitchC, and SwitchD are similar to configuration of SwitchA, and are not mentioned
here.
[SwitchA] acl number 2000
[SwitchA-acl-basic-2000] rule permit source 232.1.1.0 0.0.0.255
[SwitchA-acl-basic-2000] quit
[SwitchA] pim
[SwitchA-pim] ssm-policy 2000
Step 5 Configure static SSM mapping rules on the Switches connected to hosts.
# Map the multicast group in the range of 232.1.1.0/24 to Source 1 and Source 3.
[SwitchD] igmp
[SwitchD-igmp] ssm-mapping 232.1.1.0 24 133.133.1.1
[SwitchD-igmp] ssm-mapping 232.1.1.0 24 133.133.3.1
# Check the information about SSM mapping of specific sources and group addresses on
Switches.
<SwitchD> display igmp ssm-mapping group
IGMP SSM-Mapping conversion table of VPN-Instance: public net
Total 2 entries 2 entries matched
00001. (133.133.1.1, 232.1.1.0)
00002. (133.133.3.1, 232.1.1.0)
Total 2 entries matched
Step 6 Verify the configuration.
# The Receiver joins the group 232.1.1.1.
# Run the display igmp group ssm-mapping command to view the information about the
specific sources or group addresses on the Switches. Take the information about the specific
source or group address on SwitchD for example:
<SwitchD> display igmp group ssm-mapping
IGMP SSM mapping interface group report information of VPN-Instance: public net
