Hello Hafix,
I noticed that your subnet masks don't match on both ends of the serial link.
R6 has /25 and BB1 has /24.
Thus R6 thinks BB1 is in a different subnet and it will fail the
source update validation check.
I'm not sure if your subnet mask was a typo or intentional.
If typo change the mask to /24.
If intentional type "no validate-update-source" under the RIP process
of R6 and it will ignore that BB1 is on a different subnet.
Can you run a debug ip rip before and after and send us the output?
Thanks,
Greg
