Unconnected PoPs

In a multi-PoP network, PoPs must be able to exchange openR packets either on wired or wireless path. Otherwise, DNs/CNs might not receive the IPv6 address allocation and do not onboard to E2E Controller. The reason is: Controller sends the Prefix Allocation message to one of the PoPs and expects the message to reach other PoPs through openR.

In some cases, PoPs might be isolated temporarily, especially while building the network. Below figure is an example that shows two unconnected zones.

To facilitate such a scenario, a new configuration parameter flags.enable_pop_prefix_broadcast has been introduced in this release. This parameter supports the following Boolean values:

  • true - When the value of this parameter is set to true, E2E Controller sends the prefix allocation message to all PoPs individually.

  • false -When the value of this parameter is set to false, E2E Controller sends the prefix allocation message to one of the PoPs.

The default value of this parameter is false.

Its important to set this flag back to false when there is a wired or wireless path between PoPs.

flags.enable_pop_prefix_broadcast parameter can be modified from E2E Controller tab as shown below
