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 rou
ting table. Why ????? Since R2 and R6 is the route-reflector-clients of R1, I d
o 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.
