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 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?
