The Router only has one M.A.C Address and One IP Address But, the Router can have many Connections ( Devices using the network ) That may shoe up as their IP Addresses. But the Router only Has One IP Address

How does a cisco router recognize its own traffic?
Source or Destination MAC address
What is a Mac filter list?
It is a list on your internet router that filters computers by their MAC address, which is the fingerprint of the network adapter.
In an IPv4 environment what information is used by the router to forward data packets from one interface of a router to another?
It uses the MAC address, Media Access Control. Every packet sent from a computer contains its MAC address. The router stores this in its routing table. When it receives a packet with a destiation address of that MAC address, then it forwards it to that computer. This is called NAT, Network Address Translation. It uses the Destination IP address
Which feature that you configured on the Linksys WRT300N makes you feel the most secure and why?
MAC address filtering uses the MAC address to identify which devices are allowed to connect to the wireless network. When a wireless client attempts to connect, or associate, with an AP it will send MAC address information. If MAC filtering is enabled, the wireless router or AP will look up its MAC address a preconfigured list. Only devices whose MAC addresses have been prerecorded in the router's database will be allowed to connect.
Can you say that router is a bridge?
no a bridge does not use a IP address, it uses MAC address', rousters or layer 3 uses ip address.
Why does the switch between Host and the router not require configuration with an IP address to forward packets?
If a switch is connected to a router then the MAC address of the router is known to the switch through that port. A host takes advantage of this by using the default gateway address (the address of the router) which the switch "knows" by its lookup table. Therefore, the switch can learn the address automatically and no configuration is necessary.
What would happen when you manually added an entry you entered the correct i p address but the wrong Ethernet address for that remote interface?
Once the router/adaptor received the destination IP address (even if we entered in the incorrect MAC address) the router/adapter would remove the IP address from the Ethernet frame and using ARP, would get the correct MAC address of the destination
What is the use of PSP's Mac address?
Sometimes a router has the option to exclude all connections apart from certain specific devices. It is those devices' MAC addresses that you will need to enter in order for the router to indentify them.
