Consider a router that interconnects three subnets: A, B, and C. Suppose all of the interfaces in each of these subnets are required to have the prefix 212.1.104.0/21. Suppose subnet A is required to support 1000 interfaces, and subnets B and C are each required to support 500 interfaces. Provide network addresses for A,B and C (in the form a.b.c.d/x) that satisfy these constraints.

Consider the following Class C Network ID192.168.1.0How many bit should be borrowed if maximum of hosts in each subnet is 50?Perform the complete subnetting exercise showing Network IDs, Broadcast IDs and IP address range in eachsubnet.

32. Consider the network shown below. Suppose AS3 and AS2 are running OSPF for their intra- AS routing protocol. Suppose AS1 and AS4 are running RIP for their intra-AS routing protocol. Suppose eBGP and iBGP are used for the inter- AS routing protocol. Initially suppose there is no physical link between AS2 and AS4. a. Router 3c learns about prefix x from which routing protocol: OSPF, RIP, eBGP, or iBGP? b. Router 3a learns about x from which routing protocol? c. Router 1c learns about x from which routing protocol? d. Router 1d learns about x from which routing protocol? 3b 3c AS3 3a 1a 4c 1c 1₁ 4b AS4 1d AS1 1₂ 4a 1b X 2a 2c AS2 2b

Suppose A is connected to B via an intermediate router R, as in the previous problem. The A-R link is instantaneous, but the R–B link transmits only one packet each second, one at a time (so two packets take 2 seconds). Assume A sends to B using the sliding window protocol with SWS = 4. For Time = 0, 1, 2, 3, 4, state what packets arrive at and are sent from A and B. How large does the queue at R grow?

Each active interface of Distance vector gets frequent transmissions of the whole routing table that Distance vector maintains. The link status protocol broadcasts information about the state of a router's own connections to all other routers in the network. Each statement has two ideal examples that show how the Link state and the Distance vector may be utilized in a number of circumstances.

A router receives a packet with destination address 205.12.48.91 Show how it finds the network and the subnetwork address to route the packet. Assume the number of subnetwork required is four.

Implement in Packet Tracer a network of a fictitious organization with the following characteristics: - The organization will be made up of 4 units: 3 local Ethernet networks + 1 remote Ethernet network (via the Internet)- Local dependencies must connect to each other through a Backbone (links) between Switches- There must be 2 VLANs in 2 local dependencies- Throughout the organization there must be 2 IP networks with 2 subnets each. The different IP networks must communicate with each other.- A static routing method or a dynamic routing method must exist- The remote unit must be integrated into some IP network through a VPN link- Each local office must have IP telephony (VoIP). At least one IP phone for each unit.- In each unit there must be at least 5 user PCs- Each PC must have Automatic IP configuration (DHCP)- DHCP, DNS and Web Servers must exist - All rooms must have access to the Internet through NAT-PAT- There must be a Wi-FI network in each unit
