Also, the DHCP servers need to be configured with the proper IPv4 and IPv6 address information and the correct DHCP
options for both legacy DOCSIS, and DOCSIS 3.0 devices.
Note: In configuring the MAC domain in the procedure above, the IP Provisioning Mode was set to IPv6 only. To support
legacy DOCSIS 2.0 CMs on the same channels in the MAC domain, IPv4 addresses must also be configured.
Configure the IPv6 on the RF:
configure interface cable-mac 1.0 ip address 10.108.0.1 255.255.224.0
configure interface cable-mac 1.0 ipv6 enable
configure interface cable-mac 1.0 ip address 10.108.32.1 255.255.224.0 secondary
configure interface cable-mac 1.0 ipv6 address 2001:db8:C408:C001::1/64
configure interface cable-mac 1.0 cable helper-address 10.50.8.3
configure interface cable-mac 1.0 ip igmp
configure interface cable-mac 1.0 ipv6 dhcp relay destination 2001:db8:C408:ED00::3
configure interface cable-mac 1.0 ipv6 nd managed-config-flag
configure interface cable-mac 1.0 ipv6 nd other-config-flag
configure interface cable-mac 1.0 ipv6 no nd ra suppress
To display a brief summary of the IPv6 status and configuration for each interface, enter command:
show ipv6 interface brief

The following is an example of the output returned by the system when the ping command is used to test connectivity:
ping ipv6 2001:db8:C408:C001::1
Sending IP ping to: 2001:db8:C408:C001::1
ping (2001:db8:C408:C001::1): 100 data bytes
