Abstract:
1. A method comprising: identifying, by a network analysis system, a first destination address of a first tunnel from configuration data associated with a first router, tracing, by the network analysis system, the first destination address to determine a first physical interface corresponding to the first destination address from routing information associated with the first router, determining, by the network analysis system, a second router corresponding to the first destination address based on configuration data associated with the second router, identifying, by the network analysis system, a first source address of the first tunnel from the configuration data associated with a first router, tracing, by the network analysis system, the first source address to determine a second physical interface corresponding to the first source address from routing information associated with the second router, and enhancing, by the network analysis system, a model of a physical topology of the network based on the determination of the first physical interface corresponding to the first destination address and the second physical interface corresponding to the first source address.
