Hello!
While experimenting with tables I've noticed that number of preferred routes
in 'show protocol all ...' output is shown incorrectly.
Configuration is simple:
table T_ITCONS;
protocol bgp ITCONS {
table T_ITCONS;
passive;
local as MyASN;
neighbor 193.25.180.17 as 25372;
rs client;
prefer older on;
import all;
export none;
}
protocol pipe P_ITCONS {
table master;
mode transparent;
peer table T_ITCONS;
import where bgp_path.last = 28773;
export none;
}
I got 9 routes in T_ITCONS table, 2 of them are exported to master table:

'show protocol all ITCONS' shows sum of them, i.e. 11 preferred routes and that
is incorrect:
bird> show protocol all ITCONS
name proto table state since info
ITCONS BGP T_ITCONS up 2016-03-31 18:11:33 Established
Description: IT Consulting LLC
Preference: 100
Input filter: ACCEPT
Output filter: REJECT
Routes: 9 imported, 0 exported, 11 preferred
[...]
I'm trying to figure out what's happening in nest/rt-table.c.
Any help will be kindly appreciated! Thank you!
