  • PID—HA-RPHY

Information about RPD IPv6

The CableLabs’ MHAv2 standards requires CCAP Core and RPD must support both IPv4 and IPv6, which means the Remote PHY Signaling between the CCAP Core and RPD is able to run on both IPv4 and IPv6 networks.


Note

  • CCAP Core can support IPv4/IPv6 dual stack.

  • RPD can support either IPv4 or IPv6 network.

  • RPD does not support IPv4/IPv6 Dual Stack at the same time.

  • RPD will try IPv6 connection first. When DHCPv6 failed, RPD will try DHCPv4.

  • For single RPD, all the server addresses, protocols to communicate with it must be in the same IP version.

Configure RPD IPv6 Unicast Online

This section describes how to configure RPD IPv6 Unicast Online on Cisco cBR-8.

Configure Unicast IPv6

To configure Unicast IPv6, complete the following procedure:

  1. Enable IPv6 unicast routing.

    configure terminal 
ipv6 unicast-routing

  2. Configure IPv6 Address on DPIC interface.

    configure terminal 
interface TenGigabitEthernet slot/1/port 
ipv6 enable 
ipv6 address ipv6_address

Configure RPD core interface

To configure RPD core interface, complete the following procedure:

configure terminal 
cable rpd name 
identifier rpd_mac 
core-interface tenG_interface 
principal  
rpd-ds id downstream-cable controller profile id 
rpd-us id upstream-cable controller profile id

Configure IPv6 PTP Clock Option

To configure the IPv6 PTP Clock Option, complete the following procedure:

  1. Configure CBR as PTP secondary, see the configuration example below:

    configure terminal
    interface Loopback1588
        ip address 158.158.158.5 255.255.255.255
    ptp clock ordinary domain 0
        servo tracking-type R-DTI
        clock-port slave-from-903 slave
        delay-req interval -4
        sync interval -5
        sync one-step
        transport ipv4 unicast interface Lo15888 negotiation
        clock source 10.90.3.93

    Note

    CCAP-Core as PTP secondary can only support IPv4.

  2. Configure R-DTI for PTP IPv6.

    configure terminal 
ptp r-dti number 
ptp-domain domain 
clock-port number 
ethernet number 
transport ipv6  
clock source ipv6 address gateway ipv6 geteway

    Note

    • PTP domain and 1588 primary have same domain number.

    • Clock source IPv6 address is 1588 primary IPv6 address.

    • Gateway is next hop to 1588 primary, and it is optional.

    • For RPHY Shelf 7200, user can use ethernet 1 for all 6 eRPDs in a RPD linecard, or use ethernet 1 to 6 for these eRPDs.

  3. Associate R-DTI with RPD configuration.

    configure terminal 
cable rpd id 
r-dti number

Verify IPv6 PTP Clock Option Configuration

To display the CBR PTP Status, use the show ptp clock running command as shown in the example below:
