• IPv6 Multicast is used between the IoT FND or CE and the Cisco Resilient Mesh endpoints when performing:
• Software upgrade of the endpoints
• Demand reset messages
• Demand response messages (there could be more than one group for this per meter)
• Targeted pings (group of meters on a given feeder, for example)
• Group of meters with the same read time/cycle
• Each PAN is a multicast group with the unicast-prefix-based multicast address (RFC 3306)
• The head-end router routes (PIMv6 SSM) all multicast traffic to the unicast-prefix-based multicast address to the CGR (MLDv2)
• CGR multicast agent receives the multicast
The following guide shows an overview of the Multicast operation in an IPv6 FAN:
Figure 11: Multicast Operation
For sample configuration, see Sample Router Configuration, on page 62.
For more on dot1x, see show dot1x all details, on page 38.
Forwarding Multicast Traffic
There are two ways to forward multicast traffic to a CGR running Cisco IOS from the head-end:
• Configure the CGR as multicast client where the tunnel is configured with ipv6 mld join-group.
• Enable IPv6 multicast routing on the and configure it as a PIM6 router. This is the preferred method.
