While running a single routing protocol throughout your entire IP internetwork is desirable, multi−protocol routing is common for a number of reasons, such as company mergers, multiple departments managed by multiple network administrators, and multi−vendor environments. Running different routing protocols is often part of a network design. In any case, having a multiple protocol environment makes redistribution a necessity. Differences in routing protocol characteristics, such as metrics, administrative distance, classful and classless capabilities can effect redistribution. Consideration must be given to these differences for redistribution to succeed. Prerequisites Requirements There are no specific requirements for this document.

...office and University Campus network. The Biology Lab is running RIP protocol, whereas the Fund-raising office is running OSPF routing protocol. The new Genome4U Lab network is decided to run on EIGRP routing protocol. The edge router of this network is used to redistribute the RIP, OSPF and EIGRP routes. It will also be used to provide internet access to the Genome4U Lab network through the University Campus Network. Network Design As shown in the figure below, the Biology lab network, fund-raising office network and the University Campus network would be connected to the edge router of Genome4U lab network. The Genome4U edge router would be running multiple routing protocols i.e. EIGRP for internal network, RIP for redistribution with Biology Lab network, OSPF for redistribution with Fund-raising office network. The interface facing the Biology lab network would be configured with RIP protocol, whereas the interface connected to the Fund-raising office network would be configured with OSPF protocol. The interface connected to the Genome4U lab network would be running EIGRP routing protocol. Redistribution will be configured in the edge router. RIP and OSPF will be redistributed into EIGRP LAN with two way redistribution i.e. the redistribution of routes will be done both ways, redistributing EIGRP routes into RIP and OSPF LAN and RIP, OSPF routes into EIGRP LAN. A default route will be added in this router to route all internet traffic to the University Campus Network for internet...

...project teams in the lab. Router-EIGRP routers, as shown in the figure above, are the internal routers of the research lab network. Router-EIGRP/OSPF and Router-EIGRP/RIP are the routers that are at the Fund raising office interface and the Biology lab interface. The file servers are where the data files of the volunteers will be kept. The figure above represents an overview of the internetwork routing of the Research and Biology Labs and the Fund Raising Office. The Router EIGRP/RIP is responsible for route redistribution between EIGRP network and RIP network and also between the research lab and biology lab. Likewise, Router OSPF/RIP redistributes routes between the biology lab and the fundraising office. Redistribution between EIGRP and OSPF is required by the fringe router of the Fund Raising Office and the Research Lab. 2. What information will you redistribute between routing protocols? When there is a network with multiple routing protocols present, the must be a process of route redistribution. The dissimilar segments of the network will learn routes based on the protocol that is configured within them. Route redistribution aids spreading this knowledge in a way that it is comprehended by other segments of the network as well. There must also be a redistribution of routes learned by EIGRP to RIP in a way that it is comprehendible to RIP and vice versa. For this, a default-metric or definitive metric specifically for each redistribution, would meet the need. 3. Identify...

(10 points) Interior | Exterior | Distance Vector | Link State | Path Vector | Standard | Proprietary | Standard | Proprietary | Standard | RIP | EIGRP | OSPF | BGP | | 2. Should the individual buildings be connected to the Administration Building at Layer 2 or Layer 3? (10 points) The individual building should be connected to the Administration building at layer 3 because each building has their own subnets in the new IP scheme. 3. If the individual buildings should be connected to the Administration Building at Layer 3, which routing protocol or protocols should be used? (10 points) When selecting a routing protocol, one important criterion is how quickly the protocol adapts to changes in the network and resource allocation. EIGRP is a distance vector protocol and would be a good routing protocol to use because the network devices are Cisco based. EIGRP is fast, consumes little resources, supports VLSM, and scales well. EIGRP only works with Cisco Systems or you will immediately be faced with multiple routing protocols in your network. 4. Apply the concept of Cisco Enterprise Architecture to the new network design. Which of the six major functional areas apply to this network? Draw a diagram similar to the figure in the textbook in Chapter 3 that illustrates the...

...Kelly Keys NT2640 Fri. Night Project Paper 1. Routing tables and how the router will perform a route lookup: a. Routing Table Format- A routing table is used by TCP/IP network routers to calculate the destinations of messages it is responsible for forwarding. The table is a small in-memory database managed by the router's built-in hardware and software. Each IP address identifies a remote router (or other network gateway) that the local router is configured to recognize. For each IP address, the routing table additionally stores a network mask and other data that specifies the destination IP address ranges that remote device will accept. Home network routers utilize a very small routing table because they simply forward all outbound traffic to the Internet Service Provider (ISP) gateway which takes care of all other routing steps. Home router tables typically contain ten or fewer entries. By comparison, the largest routers at the core of the Internet backbone must maintain the full Internet routing table that exceeds 100,000 entries and growing as the Internet expands. b. Routing Lookup Mechanism- c. Classful vs. Classless Routing- Classful Routing, which is sometimes called a classful network. If you are using a classful routing protocol then all of your networks are in different classes and are separated by a router. Remember that the useable IPv4 address ranges are divided into classes. Class A 1-126, Class B 128-191, and Class C 192-223. So when we talk about...

...Phase 1: Identifying Requirements, Putting the Network Together Scenario NuggetLabs Industries is growing significantly. Due to space limitations, five employees currently share single cubicles…at the same time. While this is great for team building, these space limitations are now impacting business productivity. NuggetLabs has now leased an additional office building roughly 20Km from their headquarters location. While this office will eventually connect to the HQ office, it will initially be set up independently. NuggetLabs Industries has heard rumors of your ninja-like network consultation skills and has agreed to pay you an excessive amount of money to design and build their network infrastructure. Gathering Information To help guide this initial configuration, you‘ve assembled a list of requirements based on various meetings with management. * The new office will initially house 75 employees, each with their own Cisco IP Phone and PC. This office may eventually scale to 200 employees over 5 years. * The Windows admins are planning to install a new pair of redundant servers at the new office. They plan to manage all the IP addresses for DHCP on these servers and are waiting for you to tell them what IP address range they should use. * Windows admins: Jeff Service - (602) 555-1293, Mike Pack (480) 555-9382. * The new office is a two story building with the Main Distribution Frame (MDF) in the northwest corner of the first floor.

...document is not restricted to specific software and hardware versions. Conventions Refer to Cisco Technical Tips Conventions for more information on document conventions. Select the Best Path Administrative distance is the first criterion that a router uses to determine which routing protocol to use if two protocols provide route information for the same destination. Administrative distance is a measure of the trustworthiness of the source of the routing information. Administrative distance has only local significance, and is not advertised in routing updates. Note: The smaller the administrative distance value, the more reliable the protocol. For example, if a router receives a route to a certain network from both Open Shortest Path First (OSPF) (default administrative distance - 110) and Interior Gateway Routing Protocol (IGRP) (default administrative distance - 100), the router chooses IGRP because IGRP is more reliable. This means the...
