Re: Sub-interfaces and Secondary interfaces

I have a tidbit to add. Multicast is not supported on secondary networks. So you can't support protocols that use multicast on the secondary network such as WCCP or H323. Or at least you'll have to configure unicast connectivity for things like OSPF or EIGRP. Rodgers Moore ""Nabil Fares""

Re: Sub-interfaces and Secondary interfaces

You really do not have a lot of choice in the matter. The subinterface configuration can not be use unless you are running ISL encapsulation (vlans) or a point-multipoint type network on the interface. If you try to use the sub-interface setup without these the router will give you an error.
