Handling Process

At present, the display fib command output displays the following flags:
B: indicates the blackhole routes, routes with the outgoing interface being Null0.
D: indicates the routes generated by a dynamic routing protocol, such as IS-IS, OSPF, BGP, or RIP.
G: indicates the gateway routes, routes destined to a gateway.
H: indicates the host routes.

C: indicates the direct routes with the non-3-bit masks that are generated on the VLAN interface.
F: indicates the routes generated by the static ARP.
U: indicates that a specific route is unreachable.
V: indicates the routes generated on the interface configured with the destination VRF.
