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.
Claims19
A network switching device, comprising:
- at least one processing resource and at least one non-transitory machine-readable storage medium comprising instructions executable by the at least one processing resource to:
- 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;
- generate a first map between the first assigned subnet and a first intermediate subnet, the first map including a mapping of an IP address and gateway of the first assigned subnet to an IP address and gateway of the first intermediate subnet;
- and
- generate a second map between the second assigned subnet and a second intermediate subnet, the second map including a mapping of an IP address and gateway of the second assigned subnet to an IP address and gateway of the 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.
An article comprising at least one non-transitory machine-readable storage medium comprising instructions executable by at least one processing resource to:
- determine, for a network switching device comprising a first uplink interface and a second uplink interface, that an IP address range of a first assigned subnet to the first uplink interface overlaps an IP address range of a second assigned subnet to the second uplink interface;
- map a first intermediate subnet to the first assigned subnet, the first map including a mapping of an IP address and gateway of the first intermediate subnet to an IP address and gateway of the first assigned subnet;
- and
- map a second intermediate subnet to the second assigned subnet, the second map including a mapping of an IP address and gateway of the second intermediate subnet to an IP address and gateway of the second assigned subnet;
- wherein an IP address range of the first intermediate subnet and an IP address range of the second intermediate subnet are non-overlapping.
A method comprising:
- determining, for a network switching device comprising a first uplink interface and second uplink interface, that an IP address range of a first assigned subnet to the first uplink interface overlaps an IP address range of a second assigned subnet to the second uplink interface;
- mapping a first intermediate subnet to the first assigned subnet, the first mapping including a mapping of an IP address and gateway of the first intermediate subnet to an IP address and gateway of the first assigned subnet;
- and
- mapping a second intermediate subnet to the second assigned subnet, the second mapping including a mapping of an IP address and gateway of the second intermediate subnet to an IP address and gateway of the second assigned subnet;
- wherein an IP address range of the first intermediate subnet and an IP address range of the second intermediate subnet are non-overlapping.
