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).
