GET_TOPOLOGY_INVALID : BGP-LS Topology - ODL Nitrogen #17

Hi

I am trying to build BGP-LS topology of a bunch of vMx's using ODL Nitrogen release as Controller

ODL and Pathman are in the same localhost

I am able to get the BGP-LS Raw topology with below URL

/restconf/operational/network-topology:network-topology/topology/bgp-example-linkstate-topology

Also, able to see the Link state routes with the below URL

192.168.1.16:8181/restconf/operational/bgp-rib:bgp-rib/rib/bgp-example/loc-rib/tables/bgp-linkstate:linkstate-address-family/bgp-linkstate:linkstate-subsequent-address-family/linkstate-routes

My RIB-ID is 'bgp-example' and Topology is 'bgp-example-linkstate-topology' . Changed this in
pathman_sr.py and pathman_ini.py file

Modified URL in pathman_ini.py
url = '{}://{}:{}/restconf/operational/bgp-rib:bgp-rib/rib/bgp-example/loc-rib/tables/bgp-linkstate:linkstate-address-family/bgp-linkstate:linkstate-subsequent-address-family/linkstate-routes'

Modified URL in pathman_sr.py and netconf.py
get_topo = 'http://%s:%s/restconf/operational/network-topology:network-topology/topology/bgp-example-linkstate-topology' %(odl_ip, odl_port)

When Pathman is launched, it shows
GET_TOPOLOGY_INVALID - Couldn't read the topology

Attaching BGP-LS Routes and BGP-LS Raw topology for your information

Just want to check if I miss something! I see the Link-state routes and the raw topology but pathman-sr shows below error.

Both ODL and PATHMAN are in the same host and not sure why the Error says "couldn't reach odl-server"

But on the Pathman URL, it says the Topology is invalid!

@nikmon2 Can you please take a look here

Thank you

@durairajkumar I've spent about 2-3 months working with Juniper MX and ODL + Pathman/Pathman-SR but still didn't manage them to work properly... I've stuck on provisioning LSP's from Pathman. @nikmon2 tried to help me, but probably he is also busy with other things and we still didn't resolve the problems with provisioning LSP's. Still, let's try to help you.

Can you please show the configuration for the ODL you have in pathman_ini.py ? Did you change the ODL_IP to 127.0.0.1 ? Because by default it tries to connect to the ODL controller which is hosted in Cisco Cloud LAB 198.18.1.80.

Thank you for your reply

My ODL and Pathman-SR are in the same host and I have changed the IP to 192.168.1.16 which is my host IP
I tried with 127.0.0.1 but no luck
++++++
odl_ip = '192.168.1.16'
odl_port = '8181'
log_file = '/tmp/pathman.log'
+++++++++
The log shows as if it is building the nodes/links but eventually, I get "build_odl_topology ERROR: <type 'exceptions.KeyError'> error

@durairajkumar Hi Sir, did you manage to solve it? Could you help me if you have solved it? Because I also have the same problem. I already run PCEP between XRv and ODL. I also tried changing the IP address of the ODL IP in the python file but I still can't manage to run. The first picture is the log file and the second picture is the error that I got when I launched the app.

Now I would like to update that Pathman-SR can get the topology by following
#18 (comment).

The issue is solved by changing the URL of pathman_ini.py which is example-bgp-rib to bgp-example.

url = '{}://{}:{}/restconf/operational/bgp-rib:bgp-rib/rib/bgp-example/loc-rib/tables/bgp-linkstate:linkstate-address-family/bgp-linkstate:linkstate-subsequent-address-family/linkstate-routes'

Thank you.
