I understand the concept of PVLANs. All the guides I have been reading assume a simple topology with many hosts on a switch and a single router (default gateway). The router's port is designated as promisc and the hosts are configured as isolated.
I have not seen any guides using an l3 switch. Assume the config is such that the default gateway is the switch itself (the VLAN L3 interface). Does the Vlan interface itself have to be configured as promisc in this case?
VLAN 10 = Primary VLAN
VLAN 11 = Isolated VLAN
Would the default gateway's IP be put on VLAN 10 or VLAN 11? Would the VLAN 10 or 11 interface be set as promisc?
