Hello.
My config:
log syslog { debug, trace, info, remote, warning, error, auth, fatal, bug };
log "/var/log/bird.log" all;
log stderr all;
function pref_from()
prefix set pref;
{
pref = [ 5.5.5.0/24 ];
if net ~ pref then return true;
return false;
}
filter ibgp_policy {
if ( dest = RTD_UNREACHABLE && pref_from() && net = 5.5.5.10/32 )
then {
bgp_next_hop = 6.6.6.6;
bgp_origin = 0;
bgp_community = -empty-;
bgp_community.add((666,1));
accept;
print "Alias accepted: ",net;
}
reject;
}

But route is still in router;
show route receive-protocol bgp 5.5.5.10
inet.0: 5589 destinations, 5595 routes (5588 active, 0 holddown, 1 hidden)
Prefix Nexthop MED Lclpref AS path
* 5.5.5.10/32 6.6.6.6 100 I
fbr.inet.0: 125 destinations, 130 routes (124 active, 0 holddown, 1 hidden)
inet6.0: 32 destinations, 36 routes (31 active, 0 holddown, 1 hidden)
The route will be deleted from router if we restart bind. But restart also
means short-time break for all other connections (for other IPs)
Is there a way to delete route from router without restarting bird?
