OpenBGPD non prefix receive on other side
I currently have a problem with two of my Pfsense routers with OpenBGPD.
When I world a BGP session between a Cisco router and a Pfsense with an announcement of a / 22 or / 23 ad goes perfectly and the Cisco router is receiving 1 prefix.
However when I do the same operation with a / 24 specifically I receives no prefix.
I find no filtering the side of my Cisco router that could cause such problems.
Do you have an idea ?
