Thank you, this is exactly what I needed! Just made a simple bash script to clean BGP and it worked. Quite sure it could be better, but for my case it is good enough :) #!/bin/bash birdc sh pro | grep start | grep dynbgp | cut -d " " -f1 | while read line || [[ -n $line ]]; do birdc disable $line done birdc configure От 12 марта 2023 г. в 13:33:45, Maria Matejka via Bird-users ( bird-users@network.cz) написал: Hello! IIRC, the right way to do it is to call disable X; for X in all protocol names you want to clear, and then request reconfiguration which should clear them. BTW thank you for pointing at this feature. There is currently no automatic test suite for dynamic BGP and we should definitely add it. Maria On 3/12/23 09:19, Valery Lutoshkin wrote:

Hi,

I use Bird 2.0.9 to spread a special list of prefixes via BGP to an unknown list of users, so I use “neighbor range 0.0.0.0/0 <http://0.0.0.0/0> external;” and a passive mode.

In this situation, there are some dynamic protocols created by port scanners or some other one-time connections. It is not a big deal, but after some time the “show protocol” output looks huge, and I presume Bird eats more memory with several thousand connections.

The only way I found to clear those dynamic protocols was to restart Bird, but this affects real users of the service.

Is there another way to clear unsuccessful dynamic protocols? I can parse the list of it, but still I didn’t find a way to clear a specific protocol, like “clear protocol dynbgp2049” or smth. The best way would be to clear “all protocols in the start state”, but AFAIK right now there is no command like that in Birdc.

Best regards, Valery
