Hi All,

I am using proctorlabs to run some tests on private vlans and on switchport protected command.


My scenario is as follows:


R1 Fa0/1 --- Fa0/1 Cat2  fa0/2 --- Gi0/1 R2
                         Fa0/6 --- Fa0/0 R6
                         Fa0/7 --- Fa0/0 R7
                         Fa0/8 --  Fa0/0 R8


Router interfaces are in 10.1.2.x/24 network where x is routers number.

Tasks:
- Routers (R2,R6,R7,R8) should be in the same VLAN.
- R2 and R6 should talk to each other but they should not be able to talk to R7 and R8. - R7 and R8 should be able to talk to each other and also to other devices in the same vlan (when they will be added in the future).

First without any settings on Cat2 I have run ping from R1 to other routers and it was successfull.

My suggested solution. Put switchport protected on fa0/2 and fa0/6 so they should be able to talk to each other via Layer 3 device (R1). Put R7 and R8 in community private-vlan so they can talk to each other but not to R2 and R6.

Is that logic correct?


Thanks for all comments.


Regards,
Lukasz
