Quidway S7700 Smart Routing Switch
Configuration Guide - Multicast
Configuration Roadmap
On a small-scale experiment network, PIM-DM is adopted to configure multicast. In this
example, each host network segment is connected to only one S7700, so PIM silent can be used
to prevent the Hello message attack. The configuration roadmap is as follows:
1.

Data Preparation
To complete the configuration, you need the following data:

Procedure
Step 1 Create VLANs and VLANIF interfaces on the S7700s and assign IP addresses to the VLANIF
interfaces. The configuration procedure is not provided here.
Step 2 Enable IPv6 multicast on all S7700s and enable PIM-DM on all interfaces.
# Enable IPv6 multicast on SwitchA and enable PIM-DM on all its interfaces. The configurations
of SwitchB, SwitchC, and SwitchD are similar to the configuration of SwitchA, and are not
provided here.
[SwitchA] multicast ipv6 routing-enable
[SwitchA] interface Vlanif 100
[SwitchA-Vlanif100] pim ipv6 dm
[SwitchA-Vlanif100] quit
[SwitchA] interface Vlanif 101
[SwitchA-Vlanif101] pim ipv6 dm
[SwitchA-Vlanif101] quit
[SwitchA] interface Vlanif 102
[SwitchA-Vlanif102] pim ipv6 dm
[SwitchA-Vlanif102] quit
Step 3 On SwitchB, enable PIM silent and MLD on the interface connected to the user host.
[SwitchB] multicast ipv6 routing-enable
[SwitchB] interface Vlanif 201
[SwitchB-Vlanif201] pim ipv6 silent
[SwitchB-Vlanif201] mld enable
[SwitchB-Vlanif201] mld version 1
[SwitchB-Vlanif201] quit
The configuration of SwitchC is similar to the configuration of SwitchB, and is not provided
here.
Step 4 Verify the configuration.
# Run the display pim ipv6 interface command, and you can view the configuration and running
status of PIM-IPv6 on interfaces of each S7700. The display of the PIM-IPv6 configuration on
SwitchA is as follows:
Issue 01 (2011-07-15)
Enable multicast on the S7700s.
Enable IPv6 PIM-DM on each interface.
Enable PIM IPv6 silent and MLD on the router interfaces connected to hosts.
Create VLANs and VLANIF interfaces on the S7700s and assign IP addresses to the
VLANIF interfaces.
Address of the multicast group G: FF0E::1
Address of the multicast source S: 2001::5
Version of the MLD protocol running between S7700s and user hosts: MLDv1
