Multapplied SD-WAN allows you to manage the deployment of customer IP networks and define routing groups and subnets. Public IPs can be allocated to customers in the SD-WAN environments that you provide to your customers. Spaces allow child spaces to inherit IP assignments from parent spaces.
In general, IP management aids in the distribution of public IPs between spaces. It is usually not necessary to create IP allocations for private IPs.
IP management allows two main capabilities:
- Verification that IPs are only used at routing groups where the IP is valid. This prevents accidentally assigning IPs valid at one data center to bonds running on Aggregators at a different data center.
- Delegation of networks from a parent space to a child space, indicating that the child space is allowed to use the subnet and to allow users in the child space to assign IPs from the subnet to bonds in the space. This is for convenience and for security. It prevents unknown networks from being configured on a bond or private WAN space, such that the network would be announced by Aggregators or private WAN routers into a partner’s OSPF or BGP routing network. Bonds cannot be assigned public connected IPs, CPE, NAT, IPs, or routes, nor private WAN spaces configured with 1:1 NAT, port forward, or NAT gateway rules – unless the necessary public IPs have been allocated to the space.
