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. * Router 3c learns about subnet with prefix x from which routing protocol: OSPF‚ RIP‚ eBGP‚ or iBGP? eBGP * Router 1d learns about subnet with prefix x from which routing protocol? iBGP * Once router 1d learns about x it will put an entry (x‚I) in its forwarding table. Will I be l1 or l2 for this entry? Explain your answer briefly

(1) What are the bits (1s and 0s) in the mask /14? (2) If /14 is the network mask‚ how many bits are there in the network part and in the subnet part‚ respectively? (3) If /28 is the network mask‚ how many hosts you can have in such a (sub)network? (4)Why do you need a network mask in the routing table? (20 pts) 2: What are the maximum number of subnets and hosts in each case? (20 pts) a Class A; mask 255.255.0.0 b Class A; mask 255.255.192.0 c Class B; mask 255.255.192.0 d Class
Premium Transmission Control Protocol Routing
In terms of RIP operations‚ initially routers are configured with directly connected network addresses‚ whereby the packets are being routed by the classful routing protocol and are interpreted according to the subnet masks locally configured on the routers interfaces. Therefore all subnet masks within a major‚ class-level network must be consistent. RIP broadcast request retrieves RIP information on each RIP-enabled interface whereas the RIP table received is compared to its own table causing the

All the hardware or devices need to be connected each other to the Local Area Networking (LAN)‚ to enable them share one internet line to get connected to the Internet. This is a basic idea on how to connect all your hardware to the LAN. Connecting the Computers All PCs have to connect to the switch/hub‚ which are merge as a LAN. A local area network (LAN) is a group of computers and associated devices that share a common communications line and typically share the resources of a single processor

VLAN Paper Stephen C Wilburth Jr NTC 249 December 10th 2012 Chen Li VLAN Paper A VLAN (virtual local area network) is a logical grouping of network devices (servers‚ workstation‚ laptops‚ etc.) that generally have something in common‚ such as the same department or access to a particular server. Although devices in VLANs are virtually separated from each other by being placed on different segments‚ they can still communicate with each other as if they were on the same segment. VLANs are a
