You have used the no synch command on R2 but not R6. This is the way the
lab was designed. When you redistribute BGP into OSPF you will see the
route appear in the table.

Subject: ccbootcamp lab 8 Task 2 No 17
Hi,
I am configuring ccbootcamp lab 8 task 2 no17. I have the route
"172.168.70.0" in the R2's IP routing table but do not have the same route
in the R6's IP routing table. Why ????? Since R2 and R6 is the
route-reflector-clients of R1, I do not understand the different behaviour
of the R2 and R6 IP routing table. The configuration of R1,R2 and R6 is
below.
Any help is appreciated. Thanks in advance.
Paul
