| What is a routing table? | A map of how to get to different networks |
| What is the administrative difference between static routing and dynamic routing? | With static routing, network locations must be manually inputted whereas dynamic routing, network locations are updated from different routers. |
| Do the example on pg 255-256 | Did you get it right? |
| What does the C in routing tables indicate? | That network is directly connected to the router. |
| When multiple remote hosts are connected to a web server, how does the server's router differentiate between the connected hosts? | Port numbers. |
| If host A of router B's network is sending a packet to remote host D belonging to router C's network, what is the destination IP address and destination hardware address of that packet as it leaves host A? (draw it out to illustrate) | IP address will be router C and MAC address will be router B. |
| If two remote hosts are sending packets to a local server, will the source ports be the same or will the destination ports be the same and why? | The destination ports will be the same, both 80 (or 443). The source ports will be different so that the server's router can differentiate the remote hosts. |
| What does an ARP table show? | The IP addresses and corresponding MAC addresses of different host on the network |
| If a host was sending a packet to a remote network but didn't have the router's MAC address in its ARP table, what would it do? | Send out a ARP broadcast asking for the MAC address the corresponds to the default gateway's IP. |
| How are CRC and FCS related? | Cyclic redundancy check is math-ified and verified with the value in Frame Check Sequence to check a frame's integrity. |
| What happens if the value in the FCS does not match up with the CRC? | The packet gets discarded. |
| What 5 pieces of information must your router have to be a good router | the destination address of remote networks, possible route to the remote network, the best route to the remote network, neighboring routers to update tables, and a way to maintain and verify said tables |
| What is autonomous system | A collection of networks or subnets that are in the same administrative domain |
| What does IGP stand for? | Interior gateway protocol. Used with dynamic routing. |
| What does EGP stand for? | Exterior gateway protocol. It is also used with dynamic routing. |
| What is the name of the protocol used with EGP? | BGP, border gateway protocol. |
| What is the difference between where IGP and EGP operate? | IGP is in the network, EGP is out of the network. |
| What two protocols are involved in IGP? | Distance Protocol and Link state protocol |
| Put the networking papers in order. | How did you do? |
