Assume a trunked environment with two switches, S1 and S2. The swtiches are connected with a trunk port designed to pass VLAN 26. What would happen if VLAN 26 on S2 is configured as a private-vlan with the default gateway and DHCP server and default gateway as promisc ports. What if S1's VLAN 26 is configured as a standard VLAN. Would the hosts on S1 be able to communicate with the promisc ports on S2? Would they be able to communicate with the hosts on S2?

To further complicate things what if the DHCP server were to reside on S1 and I wanted S2 to have private VLANS with promisc ports as the gateway and DHCP server while still leaving S1 in a standard vlan configuration.
