What else can I help you with?
What action will a router take when it receives a frame with a broadcast MAC address?
It will not forward the frame to another network
Can a router work at layer 2?
Yes. A router will de-capsulate an frame to verify it was destined for itself. Frames are layer 2.
What are two switching functions of a router?
The router encapsulates the packet in the appropriate data link frame type for the outgoing data link. The router determines the exit interface after data encapsulation.
Why router needs mac address?
the tcp/ip frame uses the ip address to send messages between devices (computers, printers, etc) on your network. This frame is inside an ethernet frame on the network layer. The ethernet layer does not use ip addresses at all, they use mac addresses. For an ethernet frame to travel through a router, it needs a mac address. Your router actually does not need an ip address. It will respond to broadcasts. In fact sometimes it won't answer to tcp/ip requests. Its job is to deliver the datagram to its destination more than it is to answer you (your computer that is). So sometimes a router will not answer a ping, but a computer on the other side of the router will answer even if there are several router in the path.
How the router can use different frame formats to forward an IP packet?
ok
What is used locally by a router to identify each Frame Relay PVC?
LMI
Does ATM and frame relay has anything in common?
Both ATM and Frame Relay are ways to connect your local network router to an ISP
What is queueing in network?
Several computers attempting to connect to the same router at once, router processes one, then the next, then the next, etc..
Which frame relay feature is responsible for signaling standard between a router and fr switch?
LMI
How can I properly install door hinges using a router?
To properly install door hinges using a router, first mark the hinge placement on the door and frame. Use a router with a hinge template to create the hinge mortises. Secure the door and frame in place while routing to ensure accuracy. Test the fit of the hinges before attaching them with screws.
What does the router do after it determines that a data packet from Network 1 should be forwarded to Network 2?
It reassembles the frame with different MAC addresses than the original frame.
Which one had more overhead a router or a bridge?
a. Routers are more expensive than bridges. b. Routers operate at the first three-layers; bridges operates at the first two layers. Routers are not designed to provide direct filtering the way the bridges do. A router needs to search a routing table which is normally longer and more time consuming than a filtering table. c. A router needs to decapsulate and encapsulate the frame and change physical addresses in the frame because the physical addresses in the arriving frame define the previous node and the current router; they must be changed to the physical addresses of the current router and the next hop. A bridge does not change the physical addresses. Changing addresses, and other fields, in the frame means much unnecessary overhead.
