What can cause State/PfxRcd "(Policy)" in frr 7.5.1?

[Peter Olsson]

Hello!

I am converting a working quagga configuration into an frr configuration,
since quagga seems abandoned these days.

I run frr 7.5.1-1.1 in debian 11.2.

Most peers work fine, but a couple of critical ones get this State which I haven't seen before:
Neighbor     V         AS   MsgRcvd   MsgSent   TblVer  InQ OutQ  Up/Down State/PfxRcd   PfxSnt
x.x.x.57     4       yyyy       165         6        0    0    0 00:01:07     (Policy)        9
x.x.x.77     4      zzzzz        10         4        0    0    0 00:01:07     (Policy)        0

I'm trying to understand what this means, but haven't found anything so far.

The only interesting thing I can see is that the affected peers are using
a private AS number on either itself or the other side.
Could that cause the "(Policy)" State?

Thanks!
