Private Vlans and trunk mode

if we have a primary vlan 100 associate with it

vlan 11 over {fa0/2 work as host mode} , vlan 12 over {fa0/3 work as host mode} they work as secondry community vlan

and vlan 13 as isolated secondry vlan over {fa0/4 host mode}

How we can route between private vlans 11,12,13 and {vlan 50 fa0/5 access mode}

cloud we use the fa 0/1 which connected to L3 device as promiscouous mode and trunk mode at the same time or what ... ??

and

Re: Private Vlans and trunk mode

Private vlan's are all on the same subnet, so from what you are writing I see:

100-------------------------------

| | |

| | |

11 12 13

Fa0/2 fa/03 fa0/4

and you want to route to Vlan 50, correct?

In that case you need to trunk vlan 100 to a vlan interface and make sure that vlan 50 also has a routed interface on the same device.

Re: Private Vlans and trunk mode

thanks for your answer

but can we make the intreface of primary vlan100 (fa 0/1) work as trunk and in promiscuous mode at same time

Hint :- the interface fa0/1 the one which connected to L3 device
