Hello, You can use an additional table. And attach your and static protocols bgp there. And do not pipe those prefixes to your main table. On Thu, Sep 17, 2020 at 4:00 PM Robert Sander <r.sander@heinlein-support.de> wrote:
Hi,
I have the task to configure BIRD to be able to announce a more specific prefix temporarily to our BGP peers.
Currently we announce a /22 and want to be able to flip a switch and announce one /24 from that /22.
As we partition the network internally I cannot use the prefixes learned for the BGP announcements.
Currently there is one static protocol that contains the /22 and the export filter looks at the protocol name.
I was thinking about setting up another static protocol and enable it if needed. But the /24 is also used internally and therefor the preferred route in the table, even when the static protocol is enabled. This means I cannot filter on the protocol name in the export filter. I cannot filter on the prefix itself as it must not be exported always.
How do I achieve that?
