The traffic on RMEs is marked by the vendor implementation (configuration functionality is not available). If required, traffic can
be remarked on the CGR.
IPv6 Multicast Forwarding
RMEs deliver IPv6 multicast messages that have an IPv6 destination address scope larger than link-local when using a Layer-2
broadcast. When RMEs receive a global-scope IPv6 multicast message, the node delivers the message to higher layers if the node is
subscribed to the multicast address. RMEs then forward the message to other nodes by transmitting the same IPv6 multicast message
over the mesh interface. RMEs use an IPv6 Hop-by-Hop option containing a sequence number to ensure that a message is not received
and forwarded more than once.
Group Multicast
Group multicast can be used to control a specific group of devices by multicast. The devices in one group can cross multiple PANs.
This feature is supported on CGEREF2/CGEREF2PLUS/CGEREF3/CGERFPLCREF3 with Cisco Resilient Mesh Release 6.2.
This feature only works when MPL is enabled.
Note
In the following figure, headend services are composed of the third-party application server and FND. Headend router are used for
managing and communicating with all nodes in multiple PANs. In an application data collection system, there are multiple groups
crossing multiple CGRs to collect different data in the field. The nodes in a group intersperse in multiple PANs.
The group multicast configuration is supported on FND or application server. FND manages the group multicast addresses table
based on customer’s configuration, while the application server managers the group multicast addresses.
