Hi,

Observing "build_odl_topology ERROR: <type 'exceptions.KeyError'>" in pathman.log . Also i do not see any topology or any option to create path in web browser connected to pathman-sr.

Please find below pathman log.

Hi, A. Can you share the output for the pcep and bgp-ls topology?

B. What router-os, versions are you using?

It's hard to say what's wrong without that. But I would check:

  1. Is your bgp-ls reported router-id the same as your pcep address/id? Not having them match should not cause a match.
  2. You have a lot of pseudo nodes being reported, and I would have expected some networks being logged.

Cheers, Niklas

abhinavp001 commented 6 years ago

Hi Niklas,

Please find attached pcep and bgp-ls topology. Is SR-PATHMAN uses /restconf/operational/network-topology:network-topology/topology/example-linkstate-topology or /restconf/operational/bgp-rib:bgp-rib.

As i do not see SID value in linkstate-topology. but they are available in bgp-rib output

Hi Abhinav,

Router-ID's are fine and so is the node-format.

It looks like the issue is related to the format of the reply to:

/restconf/operational/bgp-rib:bgp-rib/rib/example-bgp-rib/loc-rib/tables/bgp-linkstate:linkstate-address-family/bgp-linkstate:linkstate-subsequent-address-family/linkstate-routes

This is the URL used to find SIDs from bgp-rib, and I suspect that your fields may be different than what I expect them to be.

Can you share that reply?

Cheers, Niklas

abhinavp001 commented 6 years ago

Hi Niklas,

Please find output attached .

Regards, Abhinav linkstate-routes.txt

nikmon2 commented 6 years ago

Thanks Abhinav, I have identified the issue; some nodes are missing a tag in their output.

Stay tuned.

Cheers, Niklas

nikmon2 commented 6 years ago

Fixed, please pull new version and let me know if it works for you.

Cheers, Niklas

abhinavp001 commented 6 years ago

Hi Niklas,

Thanks, crash issue is resolved. But still i do not see topology and other UI option after connecting through URL.

On a linux machine i have installed ODL and SR_PATHMAN and tried to access it through VNC server connected to SR-PATHMAN.

Could you please point if i am missing some setting ? Followed all steps in Wiki and there is no error message reported in pathman.log.

used below command to link app.js

pathman-sr-master]# sed -i 's/localhost/10.35.227.120/g' client/pathman_sr/js/app.js

Regards, Abhinav

Hi Abhinav, Messages look OK. Topology map should be displayed even if SIDs are missing. These are the steps to run:

  1. On your host, assuming it's IP is: 10.35.227.120, start the server: 
    ./rest_server_v6.py
  2. Point your browser to http://10.35.227.120:8020/cisco-ctao/apps/pathman_sr/index.html

I will run a test on your data and see if I find somehting else.

Cheers, Niklas

nikmon2 commented 6 years ago

Hi Abhinav,

I took your example-linkstate output, put in a file called topofile.py, and added "topo = ":

topo = {
    "topology": [

Then in pathman_sr, line 1114, I added and import from topofile:

    global my_topology
    from topofile import topo

Then a few lines below:

    try:
       #  my_topology = get_url(get_topo)
        my_topology = topo

This is enough to get your Topology View to display.

Cheers, Niklas

nikmon2 commented 6 years ago

Looking at your topo, it seems all your links are shared broadcast networks - not point-to-point links. The name.01, name.02 etc are pseudo nodes for the shared networks.

If you configured your links to be point-to-point, which they seem to be, the pseudo-nodes would disappear.

Under router isis:

 !
 interface GigabitEthernet0/0/0/1
  point-to-point
  address-family ipv4 unicast
  !
  address-family ipv6 unicast
  !
 !

Cheers, Niklas

Hi Niklas,

Shouldn't sr-pathman update topo_data.py file everytime it runs sucessfully. In my case it is not getting updated.

Still i do not see topology in browser. nor any other option. Seems that something wrong in my setup. Please find attached screen shot of browser.

I am not using Cisco router but some other vendor router will it have any impact.

Regards, Abhinav browser output

nikmon2 commented 6 years ago

Hi Abhinav,

  1. The topo_data.py file is not updated. It was used in a previous version that had geo-coordinates for routers.
  2. You should always see something in your browser. The app is split in a front- and back-end. The UI is found at your http://localhost_ip:8020/cisco-ctao/apps/pathman_sr/index.html, after that the rest-server has been started. (./restserver_v6.py) The UI should display an error if the backend has issues.
  3. Router vendor should not matter much, but the reply format may be different than what I expect it to be. That said, I used your output and generated a topo. https://github.com/CiscoDevNet/pathman-sr/blob/master/dCloud/media/cloud_Workstation_252_202504CA.png
  4. There is an issue with path setup and pseudo-nodes, but that is only an issue after you have your topology up. I have not found a good solution for that yet.

Cheers, Niklas

Hi Niklas,

Today observing below issue, could you please help to resolve it ?

Error: http://localhost:8020/cisco-ctao/apps/pathman_sr/js/app.js: ReferenceError: Can't find variable: angular

Regards, Abhinav

nikmon2 commented 6 years ago

Hi Abhinav,

That is not the correct link, but it should display the actual file app.js.

This is the link: http://localhost:8020/cisco-ctao/apps/pathman_sr/index.html This Dockerfile shows what's needed to make pathman sr run on CentOS, Ubuntu would be similar.

Cheers, Niklas

abhinavp001 commented 6 years ago

Hi Niklas.

Closing this issue , as issue is resolved thanks for your support.
