Patent ID: 8018854

Claim:
A method for testing packet switched networks, comprising: establishing a first network path associated with a first device and a local device, the first network path including at least a first router, a second router and a data link layer switch, the first device being on a first network; establishing, in the first router, a first static route along the first network path, the first static route pointing to the first network and referencing a first next-hop gateway associated with a first logical path to the first device; establishing, in the first router, a second static route along the first network path, the second static route pointing to an address of the first device and referencing the second router as a second next-hop gateway associated with the first logical path to the first device; preventing any packets received at the first router from the first device via the first static route to reach the local device; allowing packets received at the first router from the first device via the second static route to reach the local device; and directing packets sent by the local device and destined for the first device to a test set using the second static route.
