Chapter 9-Intro to IP routing
Cards in this deck (19)
- 1What is a routing table?A map of how to get to different networks
- 2What 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.
- 3Do the example on pg 255-256Did you get it right?
- 4What does the C in routing tables indicate?That network is directly connected to the router.
- 5When multiple remote hosts are connected to a web server, how does the server's router differentiate between the connected hosts?Port numbers.
- 6If 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.
- 7If 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.
- 8What does an ARP table show?The IP addresses and corresponding MAC addresses of different host on the network
- 9If 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.
- 10How 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.
- 11What happens if the value in the FCS does not match up with the CRC?The packet gets discarded.
- 12What 5 pieces of information must your router have to be a good routerthe 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
- 13What is autonomous systemA collection of networks or subnets that are in the same administrative domain
- 14What does IGP stand for?Interior gateway protocol. Used with dynamic routing.
- 15What does EGP stand for?Exterior gateway protocol. It is also used with dynamic routing.
- 16What is the name of the protocol used with EGP?BGP, border gateway protocol.
- 17What is the difference between where IGP and EGP operate?IGP is in the network, EGP is out of the network.
- 18What two protocols are involved in IGP?Distance Protocol and Link state protocol
- 19Put the networking papers in order.How did you do?
