In our environments this feature can't be used for the following reasons :
* complex, redundant network paths
* multiple firewalls between network segments
* WAN clouds or internal networks managed by third-party providers
There is no way Zenoss could figure out L2/L3 network topology just by looking at the routing tables of each device. Maybe adding a way of manually building the network map might help but I admit it woud be too much hassle for Zenoss dev team to start working on it so I don't know if it worths the effort.

Nilie,

First off, I tend to agree with your position, and am merely playing devil's advocate here.  The concept that we can't easily discern the layout of a network when we do have routing tables, and switching (essentially a complete view of layers 2-3) should allow us to determine both how frames, and packets are traversing the network.
What you are validly identifying are cases where that becomes unreasonably expensive as far as system resources, and development time.
