Methods and systems for resolving addressing conflicts based on tunnel information
Methods and systems are provided for resolving an addressing conflict between a first processor in a first network and a second processor in a second network. When an addressing conflict is detected between a first address of the first processor and a second address of the second processor, tunnel information is removed from one or more packets received from the first processor. Based on the removed tunnel information, the packets are associated with the detected addressing conflict and a translated address is determined. Based on the translated address, the packets are then forwarded.
1. A network, comprising:
a first processor on a first network that has a first address range;
a second processor on a second network that has a second address range; and
a third processor on a third network that has a third address range, other than the first and second processors, that detects a conflict between the first address range and the second address range prior to communication with the first network and the second network and resolves the conflict based on address translation information retrieved using a virtual address of a tunnel established between the third processor and the first processor, such that communication between the first network and the third network and communication between the second network and the third network is enabled,
wherein the third processor detects the conflict between the first address range and the second address range by receiving the first address range and the second address range, comparing the first address range and the second address range, and determining an overlap in the first address range and the second address range, and
the third processor determines at least one translated address without regard to the first network and second network, such that the conflict is resolved locally on the third network other than the first network and second network.
2. The network of claim 1 , wherein the third processor determines a translated address based on the virtual address of the tunnel and forwards one or more packets to the second network based on the translated address.
3. The network of claim 1 , wherein the third processor functions as a gateway.
4. The network of claim 1 , wherein the third processor resolves the conflict based on another virtual address of another tunnel established between the third processor and the second network.
