What does a native VLAN mean? Cisco documentation states that if you have VLAN1, then that is the native VLAN. What constitutes something as being native. Suppose I didn't have VLAN1, but have VLANs 4,5,6. What would make one native as opposed to the other VLANs.
Second question... If I have two IPs on a single NIC on a router and I want to create subinterfaces on it, am I assigning new IPs on the subinterfaces or using the IPs I already assigned to the NIC.
Example:
Interface Fa0/1 has 192.168.13.2 and 192.168.11.2 (secondary).
Now I am creating two subinterfaces on Fa0/1. Should Fa0/1.1 have 192.168.13.2 or a different IP on the same subnet. Likewise with Fa0/1.2 should it have 192.168.11.2 or 192.168.11.5.
