Abstract: Described herein are techniques for resolving overlapping IP addresses for subnets assigned to uplink interfaces of a network switching device. As an example, a network switching device may determine that an IP address range of a first assigned subnet to a first uplink interface overlaps an IP address range of a second assigned subnet to a second uplink interface. The network switching device may generate a first map between the first assigned subnet and a first intermediate subnet, and generate a second map between the second assigned subnet and a second intermediate subnet, wherein an IP address range of the first intermediate subnet and an IP address range of the second intermediate subnet are non-overlapping.

Abstract: Some examples relate to determining routing decisions on a network device in a SD-WAN. In an example, a network device in a SD-WAN comprising a plurality of network nodes may receive respective routing information from a respective routing agent present on each node of the plurality of network nodes. The network device may determine an overlay network topology among the plurality of network nodes. Based on the overlay network topology and the respective routing information received from the respective routing agent, the network device may determine a respective routing decision for each node. The network device may distribute the respective routing decision to corresponding network node in the SD-WAN.
