ABSTRACT:
Techniques are described for verifying a status of a set of paths through a computer network for two or more connectivity protocols. For example, a node uses a first connectivity protocol to concurrently learn information that will cause packets conforming to the first connectivity protocol and packet conforming to a second connectivity protocol to traverse a set of paths through a computer network. After learning this information, the node may verify a status of each of the paths using the first connectivity protocol. In addition, the node may verify a status of each of the paths using the second connectivity protocol. By verifying the status of the paths using both the first and the second connectivity protocols, the node may be able to quickly and accurately determine whether a path has failed.
