got some problem in RIP..

R1 and R2 are connected back to back...
i've created loopback as 1.0.0.254 for R1
                                    2.0.0.254 for R2

i've include both the serial and loopback in the RIP routing process..

what i notice...
in R1, i will see network 2.0.0.254 being send from R2
but i R2, i see nothing coming from R1 ???

any idea ?

what i notice is when i do a sh ip pro
i see different thing shown under the Routing Information Sources, on R1 it
shows the ip of the serial interface, but in R2 it shows noting...

what does the session means ?

R1 running IOS 12.2(28)
R2 running IOS 12.2(15)T17

R1
