Imagine a topology with Switch A and Switch B trunked together. Also imagine a router on a stick attached to Switch A that routes for these VLANs. The VLANs are as follows:
VLAN 1 = 10.1.1.0/24 VLAN 2 = 10.1.2.0/24 VLAN 3 = 10.1.3.0/24 (private-vlan primary private-vlan association 4) VLAN 4 = isolated private vlan, same subnet as VLAN 3 (private-vlan isolated)
The router on a stick contains the following interfaces:
G0/0 = trunk G0/0.1 = 10.1.1.1 (vlan 1) G0/0.2 = 10.1.2.1 (vlan 2) G0/0.3 = 10.1.3.1 (vlan 3)
How would I configure the trunks to pass both normal and VLAN traffic?
Will putting the trunk port between Switch A and B and Switch A and the router as:
switchport mode private-vlan trunk promiscuous
stop the trunk from passing traffic for Vlans 1 and 2? How can I configure the trunks to do these things. I would like to specify the trunk allowed vlans if possible.
