 Hello,

 I am having a problem getting IP connectivity between R6 and SW2.
From R6 I can ping R3 e0/0 which connects to SW2 fine, but I cannot
Ping the SW2 side. From R3 you can ping SW2 fine, and from SW2 it has a
route back to R6. Also oddly enough it appears that traceroute is working.
If anyone can help explain to me what I am missing I would appreciate it :)

    Thanks,

       Mike F.
