You can partition one physical interface into up to 4094 different subinterfaces, one for each VLAN.
.
Subsequently, one may also ask, how many interfaces does a router have?
two
Furthermore, how do I create a subinterface on a Cisco switch? To configure additional IP interfaces over the VLAN major interface:
- Create a new VLAN subinterface by adding a unique subinterface number to the interface identification command. host1(config-if)#interface fastEthernet 4/1.2.
- Assign a VLAN ID for the subinterface.
- Assign an IP address and mask.
Then, what are subinterfaces?
A subinterface is a virtual interface created by dividing one physical interface into multiple logical interfaces. A sub-interface in a Cisco Router uses the parent physical interface for sending and receiving data. Subinterfaces are used for a variety of purposes.
Why does my router have 3 IPS?
Having 3 IP addresses means that your system can be communicated with using three different IP addresses, and most likely means you have WiFi turned on and an Ethernet cable plugged in. One will be the loop back address (127.0. 0.1) and that is only useful on the system itself.

It's because your Ethernet (cable) network card and your WiFi network card is just that, two different network interfaces. That means that to function, each of them have to have an IP address, given by your router. The cable, WiFi, and two more from some “virtual” network interfaces that provides a VPN connection.Why do we need subinterfaces?

Router-on-a-stick is a term frequently used to describe a setup up that consists of a router and switch connected using one Ethernet link configured as an 802.1q trunk link. In this setup, the switch is configured with multiple VLANs and the router performs all routing between the different networks/VLANs.Is VLAN 1 tagged?
When the frame reaches the switch port, the switch will add the VLAN tag. The switch port is configured with a VLAN ID that it will put into the tag. Most switch ports will use this mode by default, with VLAN ID 1. This is an untagged port, configured with VLAN ID 10.How do you create a subinterface?
