Hey there,
We've got a fairly simple setup where we have two fibs. Interface routes are
in both fibs the way BSD does it. (Table 1 is the second fib, if it matters).
log syslog all;
protocol kernel {
scan time 20;
ipv4 {
import all;
export all;
table master4;
};
kernel table 1;
}
protocol kernel {
ipv6 {
import all;
export all;
table master6;
};
kernel table 1;
}
protocol device {
scan time 10;
}
setfib 1 netstat -nr:
Routing tables (fib: 1)
Internet:
Destination Gateway Flags Netif Expire
default 192.222.249.233 UGS bge0
127.0.0.1 link#5 UH lo0
127.0.0.2 link#6 UH lo1
192.222.249.232/29 link#1 U bge0
fib 0 would be the same.
An old thread seemed to imply this was because the "direct" protocol was
missing.
Adding the "direct" protocol doesn't stop this error every 20 seconds in syslog
(which seems to be related to the scan time).

Is it possible bird isn't differentiating routes learned from each fib and is
learning from both, separately, and not properly deduplicating those routes?
