Hi Yannis, I know that there are some folks using pyangbind with models that correspond to topology including rfc8346, similarly, some folks are using goyang +ygot (where using Go) for dealing with their topology models in YA

L3 Network topology in YANG

All, I was wondering if there is any network operator who exposes (dynamically?) its topology in YANG based on RFC8346 [1]. I understand that for commercial operators and purposes, may not be of any substantial value. We are assessing some available tools[2],[3],[4] on how to achieve this but we w

I know Carlos did a bunch of work to build this into Netdot, i.e. discover L2, draw usable graphs. Here's a link to the last NANOG presentation: http://www.nanog.org/meetings/nanog49/presentations/Tuesday/Vicente-netdot-presentation-nanog49.pdf John Kemp On 10/15/08 7:18 PM, Dale W. Carder wro

Network topology

Hi all I'm considering trying to come up with some means to automatically detect a networks topology and draw pretty pictures. This is somewhat boring though if a network isn't well arranged with VLANs and q-tag trunk routers and so on (It will just look like a big cloud of junk connected off
