Hi,


As far as I know, FIB is the same info from the routing table but should be "reformated into a ordered list with the most specific route first".

Having a look to several FIBs, I ve never seen most specific route first. Following example, 192.168.199.0/24 is before 192.168.199.0/32.

How is this possible?


Thanks,

Since each of these routes has a different prefix length (subnet mask), they're considered different destinations.
