Six major points of Routers

There are six major points to remember or keep in mind when working with routers or layer 3 devices. You should probably commit these to memory.

Here are the six major points

1. Routers, by default, will not forward any broadcast or multi-task packets.
2. Routers use the logical address in the network layer header to determine the next hop router to forward the packet to.
3. Routers can use access list, created by an administrator to control security on the types of packets that are allowed to enter or exit an interface.
4. Routers can provide layer 2 bridging functions if needed, and can simultaneously route through the same interface.
5. Routers provide connections between virtual LANS (VLANS).
6. Routers provide Quality of Service (QoS) for specific types of network traffic.
