Hello guys, I have a problem with having multiple FIBs in FreeBSD-9.2. I've already setup 4 FIBs in kernel, and everything is OK. I assigned each interface to one FIB and I can add routes to any of FIBs I want, and everything works fine.But my problem is, I want to assign same IP address to multiple interfaces. for example: interface em1 (in FIB-1) : 100.100.100.1/24interface em2 (in FIB-2) : 100.100.100.1/24 this should work, bacause I want each FIB's interfaces and routes to be completely separate from other FIBs' interfaces and routes. for this I do:# sysctl net.add_addr_allfibs = 0 # ifconfig em1 fib 1# ifconfig em2 fib 2# setfib 1 ifconfig em1 100.100.100.1/24# setfib 2 ifconfig em2 100.100.100.1/24 but this doesn't work as expected, and 100.100.100.0/24 route is only being added to FIB-1 (second IP assignment command doesn't work, though it returns no error).# setfib 1 netstat -rn ==> this fib has 100.100.100.0/24 entry added in it# setfib 2 netstat -rn ==> nothing is added here. Is there any way I can do this in FreeBSD? Thank you.
