Topolograph.com is an online project which can visualize OSPF/ISIS topology based on LSDB output from a single network device. Then you can not only see (and check) the shortest path from source to destination, but also see the outcome from link or node failure along the path to the destination.

ISIS DB from Nokia emtpy #34

Open laimaretto opened 1 year ago

laimaretto commented 1 year ago

Hi! I've built a lab to test the analysis on ISIS networks, but the tool complains with a "The graph is empty. Are you sure that you uploaded ISIS LSDB from Nokia".

The topology I'm using is this one:

And the DB is the one I obtained at the router P-11, which is an L2 router. EDIT: I've updated the DB output since PE-14 was missing in my original post.

Any ideas? Thanks!

Hi @laimaretto , many thanks for the commands output! I will check it shortly!

Vadims06 commented 1 year ago

Hey @laimaretto , I fixed nokia is-is templates, but I didn't find RA-15, RA-16 and PE-14 in the lsdb output, so I got only three routers on a diagram. image New templates are available on online version of Topolograph and then will be added into docker image soon.

laimaretto commented 1 year ago

Hi @Vadims06 ! thanks for the feedback. I believe I made a mistake with the previous output: somehow (don't know why) the output for PE-14 is missing but it's there, probably a copy+paste mistake; if you don't mind I've updated in the first message, the database output so it is now consistent. I believe that, if you execute again the template for the updated database, you'll see the missing PE-14 router, from the point of view of P-11.

However, let me share with you the following reasoning. It's interesting that (from the point of view of P-11) you can only see PE-13 (and hopefully PE-14 after my update), given that they both are L1L2 routers. RA-15 and RA-16 are both L1 routers, so I believe it kind of makes (a little) sense to me that you don't see them (please, bare in mind that I'm far from being an ISIS expert ;-) ).

However, let me show you first the following:

Brief database of P-11

It looks to me that PE-14 is available from this output.

If we inspect the details for that LSP, we see that it actually has some knowledge about both neighoirs P-11 (172.16.0.11/32) and RA-16 (172.16.0.16/32)

So my guess is that it should be possible to reach RA-15 and RA-16 from P-11, which is an L2 router.

Final thoughts...

Other idea would be to only analyze the DB at an L1L2 router, such as PE-14. Let me share that DB with you. You'll see that it has information about all of the LSPs.

Hi @laimaretto thank you for your feedback. A topology from PE-14 point of view image

stable_lab_isis_database_v2.txt Hello,

I have a similar behaviour, I tried to upload on an offline instance of topolograph the following topology and I also get an empty graph message, can you check if the file as such should be parseable for you ?

ailtchev commented 1 year ago

Raw file with empty Level 1 Area part included if this could cause issues. stable_lab_isis_database_v3.txt

Vadims06 commented 1 year ago

Hi @ailtchev , Many thanks for your templates. They helped me a lot. I fixed my templates, like Neighbor -> Nbr and got such beautiful topology. I'm going to apply some other fixes and will release docker-based Topolograph under 2.35.3 or 2.36 tag next week. Fixes are available on online version of the Topolograph right now. image P.S. I noticed that TE is activated, I'm thinking to introduce some new features based on TE data, like color link by Admin groups etc, could you please share what features could be valuable for you and other users of Topolograph to analyze MPLS?

ailtchev commented 1 year ago

Hello,

Thanks for the feedback, did you update only the Nokia textfsm template ?

The topology indeed looks like this in our validation network. I am planning to run it on our 800+ node network to visualise it.

For the features, admin group coloring is indeed a good way to see the current state of setup in the network.

At a previous job, I worked also on a similar app with flash displaying XML based topology. There, the aim was always to display the dynamic graph on predefined positions of the routers based on the visio base network design that I was maintaining. In a separate window, I was allowing the user to place new routers where he wanted and when the routers came back in topologies at the same place , like routers from south of the country being displayed in the bottom part of the diagram. positions were stored in db in absolute coordinates varying between (0,0) - bottom left and (1,1) - top right.

Extra features, that can be interesting to be displayed is physical interconnection between nodes using LLDP based network discovery where each node needs to be queried with napalm/netconf yang tree and where each logical link for OSPF/ISIS viewcan then displayed as a composition of N physical links aggregated in a PortChannel/ae/LAG interface. Data model can become complex and you can have a look on the proposed model from RFC8345 - A YANG Data Model for Network Topologies to see what can be used from there. Let me know if this makes sense.

Not going as far, you can parse and add as attributes Segment Routing infos available in LSDB like node IDs and interface segment labels assigned locally by each router.

More generally what vendor paying tools are proposing are visualisations of MPLS paths calculated by RSVP in decentralised mode available on the ingress nodes of these paths or centrally calculated paths based on topologies, admin group and bandwidth requirements delivered through PCE protocol. Your tool could verify if routers have correctly received calculated LSPs. You can use containerlab to play aroudn these concepts if you want to explore them further.

prod topology image And ECMP path calculation on that topology image

Vadims06 commented 1 year ago

wow! looks cool! do you have any noticeable delay in building paths on such big topology?

Vadims06 commented 1 year ago

Thank your feedback! I have a task to provide Drawio-based topology in my backlog, but first of all I would like to:

LLDP based network discovery is also challenging task, but I think it's better to let the customer gather LLDP information via napalm/netconf by themselves (so many vendors with so many LLDP's command output) and push the LLDP data on the topology (drawio?) via uniform API.

parse and add as attributes Segment Routing infos available in LSDB like node IDs and interface segment labels assigned locally by each router.

yeah, it seems to be easy - I will put it into my backlog!

If you are not against - may I add you in "topolograph's friends" email group for the chance to ask the feedback from network professional community.

ailtchev commented 1 year ago

Hello, with pleasure for the topolograph's friends ! The graph takes some to build and to be parsed shortest path doesn't seem to be a problem. I provide you my email on another well known professional network.
