ODL topology data is invalid

[ralphchen]

hi all

when i prepared everything on ODL(bgp-ld/pcep) that i can get the topology from YANG UI on opendaylight, and i run the pathman on the same node . then i opened http://localhost:8020/cisco-ctao/apps/pathman_sr/index.html it tells me topology data is invalid.

here's the pathman log on the server:

32502 2019-09-16 22:31:14.505 UTC root:pseudo_net_build INFO: [] 32502 2019-09-16 22:31:14.521 UTC root:_get_url INFO: status code: 200 32502 2019-09-16 22:31:14.521 UTC root:build_odl_topology ERROR: <type 'exceptions.KeyError'> 32502 2019-09-16 22:31:14.522 UTC root:getTopo INFO: Failed to get topo: could not reach odl-server? 32502 2019-09-16 22:31:14.522 UTC root:post INFO: {"response": [{"cause": "could not reach odl-server?", "option": "topo", "success": false}]} 32502 2019-09-16 22:31:14.524 UTC root:initialize INFO: Init 2 done - debug saved 32502 2019-09-16 22:31:14.525 UTC root:rest_interface_parser INFO: Commands Relieved: {u'option': u'list_all'} 32502 2019-09-16 22:31:14.539 UTC root:get_url INFO: Url get Status: 200 32502 2019-09-16 22:31:14.540 UTC root:listAllLsp INFO: list: [], formatted: [] 32502 2019-09-16 22:31:14.540 UTC root:post INFO: {"response": [{"list": [], "option": "list_all", "success": true}]}

it seems caused by "root:getTopo INFO: Failed to get topo: could not reach odl-server?" i'm new to ODL and pathman, any suggestion and where to start troubleshooting on it?

thanks in advance

i found the cause

the default url of bgp-rib in pathman_ini.py is example-bgp-rib

    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'

however i followed the ODL guide which is bgp-example . after i correct this, the topology is shown up.

Hello ,

I'm having trouble using Pathman SR with Junipers vMX routers. I am facing the same error as you using ODL Beryllium. can someone help me or do i need to change ODL version?
