IP Domain configuration is used to translate your private mobile network resources to the existing L2/L3 network configuration on your infrastructure.
Configuring IP Domains with Celona Edge Clusters
As explained in detail in this article, IP Domains help translate cellular wireless to existing enterprise network resources for L2/L3 traffic forwarding.
Related network policies are managed via the Celona Orchestrator: select Edge Clusters from the side-nav menu in the Orchestrator to start. From the list of clusters displayed, select the name of the Edge Cluster for which you will be configuring the IP Domains.
Toward the end of the page, you will see two options to Add Internal IP Domain or Add External IP Domain. Note that multiple IP Domains of various types can be configured on each Celona Edge Cluster.
Internal IP Domains are fully managed by Celona Edge; the default IP Domain on every Celona Edge is Internal, NAT mode. Additional Internal, NAT mode domains can be added.
Configure an Internal IP Domain
Define the
start and end IP addressof the DHCP range that will be provided by Celona Edge.Set
custom DNSservers if required. Otherwise, devices will default to usingPrimary - 8.8.8.8,Secondary - 1.1.1.1.Click
Addto save your newInternal IP Domain.
Configure an External IP Domain
External IP Domains connect an existing VLAN or subnet to a specific Device Group in your private mobile network.
The Celona Edge OS now supports DPDK to extract the best performance from the platform as well as support the following advanced networking and enterprise integration features -
Supernetting
L2 bridging for industrial applications such as PROFINET
More details on Network Requirements to support DPDK here
The Celona Edge OS support for DPDK requires additional IP addresses for Edge Cluster operations. The number of additional IP addresses needed per cluster will depend on the:
Number of nodes in the cluster
Number of IP domains configured in the cluster
Configuring your External IP Domain:
The following interfaces need to be configured to setup an External IP Domain for your devices connecting to the Celona network
VRRP ID and VRRP IP address
This interface will only be available when the edge cluster has at least 3 nodes. [Refer here for additional details on VRRP requirements to support Multi-node Edge Cluster Configuration for High Availability and Scaling.]
Users are required to provide the VRRP IP Address only. The VRRP ID is auto-populated from the last octet of the VRRP IP Address, but can be edited if necessary.
2. Edge ↔︎ Enterprise LAN data plane interface (N6/UPF)
This interface is configurable once the VLAN ID is specified as a part of the External IP Domain configuration.
DHCP is enabled by default for this interface, if VLAN ID is specified.
If a user would like to provide Static IP configuration for this interface due to the unavailability of DHCP, click the
Staticbutton to expand the section and enter the static IP address per edge node assigned to the cluster, the Subnet Mask, and the Default gateway.
3. AP ↔︎ Edge data plane interface (N3/S1-U)
DHCP is enabled by default for this interface.
If a user would like to provide Static IP configuration for this interface due to the unavailability of DHCP, click the
Staticbutton to expand the section and enter the static IP address per edge nodes assigned to the cluster, Subnet Mask and the Default gateway.
Users are required to provide values in all the fields in this section or leave all values empty.
4. DHCP Server
If DHCP is selected for all interfaces, specify the
IP address or subnetof the DHCP server in your existing network that will provide IPv4 addresses to devices in this IP Domain. Leave it blank to broadcast the DHCP request.
NOTE: Celona Edge switch interface should be a trunk port, with native VLAN untagged for management and tagged VLANs for client traffic forwarding
Once added, Celona Edge will create a corresponding VLAN sub-interface on its primary interface and request an IP address via DHCP broadcast on that VLAN. Leaving this blank connects the IP Domain directly to the default VLAN of the Celona Edge primary interface.

You are now ready to connect devices to your Celona network.
