22 NOAM IPv6 Migration

Prerequisite: The xmi and imi network should have two subnet network each, where 1st will be on IPv4 subnet and 2nd will be on IPv6 subnet.

For example:

Network name: ext-net

Table 22-1 Subnets

Name Network Address IP Version Gateway IP
ext-net-subnet 10.75.189.128/25 IPv4 10.75.189.129
ext-net-ipv6-subnet 2606:b400:605:b818::/64 IPv6 2606:b400:605:b818:6e41:6aff:fec7:80bf

Note:

The VNFM supports dual subnet, in case a subnet migrate is required, then perform the following steps.

Steps to migrate DSR NOAM on IPv6:

  1. Create DSR Noam through VNFM. Provide dual subnet network (xmi and imi) to creating the DSR Noam set up. DSR NOAM will be up and running with IPv4 network interface through VNFM and will create the IPv6 IP address in Openstack for both xmi/imi.
  2. Add the allowed address for IPv6 manually through Openstack cli command for both active/standby NOAM.

    Note:

    User should have permission to add the allowed address to port through OpenStack CLI.

    Run the following command to add the allowed address pair in port:

    openstack port set --allowed-address ip-address=<vip ipv6 address> <active noam port id>

    openstack port set --allowed-address ip-address=<vip ipv6 address> <standby noam port id>

    For example:

    openstack port set --allowed-address ip-address=2606:b400:605:b818:6e41:6aff:fec7:80cf a2d4fe19-d5e8-4a18-b08c-0057e68d2bde

  3. Follow the Dual IP Stack migration document to add the IPv6 interface for active or standby NOAM xmi, imi, and VIP.
  4. While adding IPv6 interface, use the same IPv6 IP address for active/standby xmi and imi which is created through VNFM for DSR NOAM.
    1. Go to Openstack GUI.
    2. Navigate to Network -> <network name> and locate the active/standby and vip port.
    3. Open the port to obtain the created IPv4 and IPv6 address.
