debug packets - output
by Michal Ruprich 04 Mar '21

04 Mar '21

Hi all, I am trying to debug eigrp process in FRR and I can't figure out, how to get any output from 'debug eigrp packets all'. Nothing shows up anywhere. Initially, I thought, that I will see the output directly in vtysh as the packets come, but I don't see anything. I tried to set logging to an output file - it gets created but no output in the file. I don't see anything in /var/log/frr either. Can anyone give me a hint as to where and how to get the debugging running? Or any other logging to that matter? Thanks and regards. Michal Ruprich

Disable compiling python codes in FRR
by Shahriar Basiri 08 Feb '21

08 Feb '21

Dear FRR community,I need to disable compiling python codes in FRR. I am cross compiling FRR but my toolchain doesn't have python. I think main frr codes is in c and maybe some tests and GUI are using python. is it at all possible to disable compiling python codes? Any help is really appreciated.ThanksShahriar
