Before deep into the question, please see this topology and the results of sending messages from one router to the other router:
I have succeeded in sending a message from R0 to R2 (or vice versa), R1 to R3 (or vice versa). But why I can't send a message from R0 to R3 (or vice versa)? I've already set all
redistribute static
and redistribute connected
in RIP and BGP routers (R1 and R2)
What should I do?
