Hello,
Maybe all your peers have the same AS number? BGP by default does not
pass routes among internal peers.

Hi everyone ,I'm using bird2.I wanna export 2602:feda:ab2::/48 from LL_IX
to TOHU_IX.

Hello!
I'd try:
* "show route noexport all" to see what may be the reason to drop the route
* add some logging to the filter to see why it is dropped
BTW, what version are you using? As far as I remember, the BGP attributes are
behaving differently on export in 1.6 and 2.0

Hi,
I can guess that when you export to BGP, it prepends your AS before
the filter, so your check for "bgp_path.len = 0" turns false.

Hi,The function i wrote correctly returns net.
bird> show route 2602:feda:ab2::/48 where bgp_export_all()
Table master6:
2602:feda:ab2::/48 unicast [LL_IX 02:19:31.236] * (100) [i]
via 2602:feda:ab2::1 on ll-ix
But it could be export.
