IPv6 Network design consideration
There are two sets of networks while designing the IPv6 network. one set is for the OpenR subnets (e.g.
prefix of 56 bits and partition into multiple 64 bits subnet). Each cnWave node is assigned with a subnet.
Each PoP node, besides being part of the OpenR mesh network, has a subnet assigned to it and has an
IPv6 address assigned to it as PoP interface IPv6 address.
If the operator lets the system automatically generates IP address configuration, the IP address always be
in the format of FD00:xxxxxxx, which is a standard routable private IPv6 address.
