Problem in FRR with ldpd
by shruti mathure 12 Oct '21

12 Oct '21

Respected Sir, I am Shruti Mathure. I am working on one of the projects related to FRR. I am trying to implement MPLS LDP with FRR in Core emulator. The FRR seems to run but I am having issue with ldpd, It is not running also the staticcd does not seems to run which should automatically start with FRR. I am not able to find the correct solution for it. can you let me know any solution for this if there is any changes or latest updated bugs you have fix. I am not able to find any solution on github. I am using ubuntu 18.04. Thank you, Regards, Shruti Mathure

All, This will be the penultimate request for nominations for candidates for the TSC elections. Please contact me with nominations or questions. 1) Self-nominations are welcome. 2) All nominees must be active FRR maintainers in order to stand. 3) Present TSC members must opt-out of being auto-nominated. 4) If you plan to nominate someone else, please get their approval first. I will send a final reminder in few days and then start the voting next Monday.. /a (your friendly FRR community elections officer)
