Problem 3: Intra-AS and Inter-AS Routing Consider the network shown below. Suppose AS2 and AS3 are running OSPF for their intra-AS routing protocol. Suppose AS1 and AS4 are running RIP for their intra-AS routing protocol. There is no physical link between AS2 and AS4 (as indicated by the dash line). BGP protocol, including eBGP and IBGP, is used for inter-AS routing protocol. AH 16 AS2 1d AST Assume x is a prefix connected to router 4a. Please answer the following questions: {a) What does AS stand for? Please explain what AS is. (b) What does BGP stand for? What is the significance of BGP? (c) Router 3c learns about prefix x from which routing protocol: OSPF, RIP, EBGP, or IBGP? Why? EE3706 Computer Networking, Fall 2021 (d) Router id learns about prefix x from which routing protocol? le) Please identify gateway routers in this network. There should be 2 in each AS. () Assume router id learns about prefix x, what is the AS-PATH attribute in the BGP advertisement path? What is the NEXT-HOP attribute (answer by indicating which router in this network)? (8) Now suppose there is a physical link between AS2 and AS4, and router id learns that is accessible via AS2 as well as via AS3. If id wants to reach x, based on the routing rules, will it go through la or 1b? Why
