Since NPM can now discovery topology at layer 2 it would be great if that information could be used to generate dependency information for the purposes of determining whether a node is down or unreachable. . Iea
Ideally, we would still be able to add dependencies by hand to help it along in cases where there is something like an MPLS cloud between two nodes, etc.
This would save a lot of time in situations where there is a lot of infrastructure in each location and the topology graph is easily discoverable.
