Hello,
I am having a hard time in getting connectivity through the switched network
for this lab. I can see that the trunk links are all up as required by the
lab, the allowed vlans on trunks are okay and the spanning tree looks good.
However I am not able to ping across devices like R1 cannt ping BB2 and R6
cannot ping R3. When i try to ping once in a while I'll get 1 reply (..!..).
Has anyone else faced this problem in this lab?
Below is the output of my config: (If you see in the debug output there is
only one packet recieved from BB2 in the very end)
