Hello, with this, are you sure that you are actually editing the right config file? If you do a syntax error right at the beginning of the file, just putting garbage there, does it fail? Maria On 2 December 2024 23:11:30 CET, LIU Chris via Bird-users <bird-users@network.cz> wrote:

I configured 4 bfd sessions like below, but 3 sessions are up, I check many times, those 4 session seems no any difference. I used birdc command to check "birdc show bfd sessions session" only 3 sessions, 1 session not list here. Why I configured, bird not take it.

The stranger thing: even I comment out 3 sessions in conf file, just leave one, kill bird daemon, restart bird, Use birdc to check bfd sessions, still same, the 3 sessions are up, It seems bird not read configuration file again. What would the issue be ?
