A simple ipv6 hub & spoke question..
R5 is the hub and R2 is the spoke..
Also, R1 is connected to R2 thru ethernet and R1, R2 & R5 are running
RIPng...

                               S0/0 S0/0.25
R1 <----------------> R2 <-----------------> R5
       ether frame-relay (hub)

Can anybody help me why I am able to ping R2's serial i/f connected to R5
from R1 but not R5.
In simple words i am not able to establish connectivity between R1 & R5..Am
I missing something ?
