gopcep's Issues

Config file

To ease getting started and trial this tool it would be helpful to have an example config file somewhere. It is not quite clear from textual description on how the config file needs to look like..

Even tho pcep and bgp(bgp-ls) is connected and I can see from the bgp-ls peer that it is sending data and according to the logs gopcep is receiving and treating the information found the Network Map stays empty ?

I don't have gRPC connected but I suspect that it ain't supposed to be a requirement to see the map ?

Add Routers

I tried to establish a PCEP Session but that was not successful. I assume I need to create the Router first, right? Is there another way to create a router besides the GUI? The GUI did not work for me. I was not able to save the router details.

Is it mandatory to create a Router first? Wouldn't it be better to just establish the PCEP session from the PCE client and the gopcep webui just displays the NEs which are connected?

I am quite interested in this project but I will need some upskilling in go programming before I could possibly contribute myself other than just commenting here.

panic in http server

fatal error: sync: Unlock of unlocked RWMutex

After a bit of hassle I managed to get gopcep to function. Have to control it from remote so had to hackaround in your .js and stuff to get it functioning.
But after finally getting everything up and running I attached it to a Juniper box and configured all knobs that has to be configured.. when it finally started to send bgp-ls updates gopcep broke down with the error "fatal error: sync: Unlock of unlocked RWMutex".

Complete log from start to crash:
