Hi. I've seen you commenting on the candidate-bsr branch, and at some point we'll be getting to this. But please be aware that there's a reason this branch hasn't been merged into FRR master. The code hasn't really been tested. We're currently working on getting topotato up to speed as test framework and there will be C-BSR/C-RP tests there, but this is still WiP.

I'm happy that you're using this code and it seems to do at least something useful for you, but… there were bugs, there are bugs (as evident here), and there will be more bugs. This is not quite prime time ready yet.

I know it hasn't been merged into the FRR master yet, it's still in the testing branch. I just wanted to ask a question because I don't have a good solution at the moment and I hope you have time to help. Thank you very much for your contribution, I am indeed trying to use this code and the basic functions can be used, which is great.

I am trying to make the function pim_elec_bsr_timer call pim_bsm_parse_install_g2rp effective, and it seems to be working fine at the moment. However, I am not sure if there are any potential risks.
