Hello,
There is some thingh i don't get :
> R6's interface is a Fastethernet 0/0.1(175.3.56.6/24)
> interface FastEthernet0/1.10
> encapsulation isl 10
> ip address 175.3.56.6 255.255.255.0
Have you check the right sub interface; and the vlan declared on the catalyst ?
It must be VLAN 10 for R5 fastethernet and same VLAN 10 for R6 fa0/0.10 as you
did.
Best regard
