Hi Ondrej,

Thank you for your response.

Do you mean route withdrawals for routes received from that removed protocol?
Send to other peers? This should not be an issue - when a protocol is removed
or disabled, all its routes are removed and withdrawals should be sent to
other protocols.

 

Yes, I mean withdrawals for routes received by the router from the peer running bird. The peer is directly connected with the router with a bgp session.

I am removing some static protocols and doing "birdc configure soft" but no route withdrawals are being sent for the removed prefixes. Even if I try to run "birdc reload out all", the withdrawals are still not sent since bird forgot about the prefixes already when I did the "configure soft":

bird[28196]: Removing protocol e_010_cidrs
bird[28196]: Reconfigured

If I disable the protocol with "birdc disable e_010_cidrs" without removing it from the config files, I see the esame "Remoing protocol e_010_cidrs" message in the logs and the withdrawals are sent as expected, but I expect bird to also send withdrawals when a protocol is removed from the configs without being explicitly disabled.

Do you also think this is a bug?

Best regards,

Thomás
