Re: [nznog] Dynamic network topology mapping - L2 and L3

Cariden is brilliant but a significant investment. I've had some success with Network Weathermap populated through a bunch of script generated data fiiles. Have a look at the network weathermap on the REANNZ website (not mine but the same tool). Sent from my iPhone

I have used graphviz and .dot files manually populated from CSV exports in the past with pretty good results. https://osl.uoregon.edu/redmine/projects/netdot/wiki , http://www.graphviz.org/Documentation/dotguide.pdf

All the other approaches I have used/played with required fairly significant investment into ensuring consistency in SNMP collection, MIB availability and/or entering things into product X's system (Caradin,Netcracker,amdocs).

netdot is good - but again requires inventory population via either well structured SNMP implementation accross devices or manual population https://osl.uoregon.edu/redmine/projects/netdot/wiki

The upshot of netdot and the first approach is Free. The other solutions mentioned are Megabucks and Enterprisey/Carrier market targeted.

Does anyone out there have a recommendation for a good network topology mapping application ?

I want to see a live layer 2 and 3 topology diagrams - routing and vlans etc.

juniper space used to have such a plugin but they killed it :(

the only other mention of an app capable of such a thing that I have heard of is solar winds .

Network Topology Mapper

Any advice or experience with such an app would be much appreciated.

cheers
