Currently providing customer devices with IPv6 addresses is only supported for CPEs (Router). In our opinion it's not desired to hand out IPv6 adresses to cable modems and MTAs as they don't need to be reachable from the internet and it's even more unsecure. Also it's currently only implemented for DOCSIS part, but it will be integrated for all other infrastructures (DSL, FTTH, ...) soon.
To provide your customers with an IPv6 address you need to do the following steps.
- Add IPv6 pool
- Configure NMSPrime server
- Configure CMTS
- Add mandatory DOCSIS configfile parameters
1.1. Example: Add IPv6 pool
1.2. Configure NMSPrime server
As the provisioning server doesn't need to be publicly available via IPv6 we recommend to use private addresses fd00::/8 for the management interfaces. This makes the DHCP server only public to the internal network. So connect to the server via SSH and execute following commands. Of course you can deviate from this proposal.
1.3. Configure CMTS
Enable IPv6 on CMTS, add cable helper address and establish connectivity via Gigabit interface.
1.4. Enable DHCPv6 via DOCSIS configfile
Enable the eRouter of the Cable Modem to do DHCPv6 via
