0. AS1 has the following routing table, draw the network of AS’s that these paths imply: prefix            path P1                 AS2 P2        AS4 AS5 AS3 P1             AS4 AS2 P2             AS5 AS3 P1             AS5 AS2   Assuming AS 1 accepted all the paths advertised to it, what paths does AS4 advertise to AS1? What AS is P1 in? What about P2? AS5 no longer wants to forward packets destined for prefix P1 on behalf of AS1, but it is ok forwarding prefix P2, how would it change the paths it advertises to AS1? If AS1 sends a packet to AS4 destined for P1, what path will it take? How do we know AS4 won’t forward it back to AS1? If AS1 gets the following advertisement from AS4, P1 AS4 AS1 AS2 how would it update its table? Why?

Types Of Protocols

A network protocol is a collection of rules that governs the exchange of data between devices connected to the same network. In other words, network protocols are rules that specify how devices communicate or transfer data over a network. The sender and receiver systems must obey the standards to facilitate communication between them.
