20 NOAM IPv6 Migration

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

For example:

Network name: ext-net

Table 20-1 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, incase a subnet migrate is required, then perform the following steps manually.

Steps to migrate DSR NOAM on IPv6:

1. Create DSR Noam through VNFM. Provide dual subnet network (xmi & imi) to creating the DSR Noam set up. DSR NOAM will be up & 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.

   Execute 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 document Dual IP Stack migration to add the IPv6 interface for active/standby NOAM xmi, imi and VIP.
4. While adding IPv6 interface, use the same IPv6 IP address for active/standby xmi & 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 & vip port.
   3. Open the port to obtain the created IPv4 & IPv6 address.
