Hello, 

I would like to know what's the meaning of the flags in the routing table? it is D for some routes, and RD for others.

Do you have any suggestions for that?

Thank you in advance!

@sim_157 hi,
 R: indicates that the route is an iterated route.
 D: indicates that the route is delivered to the FIB table.
which means that, when a route is tagged as R, the next-hop ip address is not directly connected, the next-hop IP address is determined by the other routing item. D means the route has been delivered to the FIB table, the router will forward the traffic depending on the fib item,

Hello,

The Flags displayed in the routing table have different meaning depending on the letter:
D is indicating the routes delivered to fib
R is for iterated routes
and DC is for DHCP client.
From these basic flags come other variations like RD, the one you specified.

Hope this helps.
