Hello Team,
I know I'm in a wrong channel here but I just wanted hear your suggestion.
I have 4 routers( diagram below) R1 <-->R3 has a iBGP peering while R3<-->
r4 has eBGP peering.. R4 advertising his loopback and R3 was able to
received it through eBGP updates and R1 was able to learned a route too
from R3 iBGP updates. now the issue here R1 can't ping the learned routes
from R3. please take a look at the config. and Also based on debug i seen
in R2 the packets destined for 11.11.11.11 IP's is unroutable .. which i
thought BGP work like a tunnel. please help me.
R1-->R2-->R3-->r4

here's the log I got on R2 while doing a debu ip packet.

Hi,
I just checked the workbook section initial configs, and they seem to be
the final configurations after the workbook is completed. Could someone
please check and make sure that this is the case.
Thanks,
