Ospf Example Network Diagram
Free Printable Ospf Example Network Diagram
The following example illustrates how to configure single area ospf network.
Ospf example network diagram. Areas are a logical collection of routers that carry the same area id or number inside of an ospf network the ospf network itself can contain multiple areas the first and main area is called the backbone area area 0 all other areas must connect to area 0 as shown in the diagram below. Ospf routes the ip packets within a single routing domain. The first diagram shows a network segment with an inter area router connecting areas 0 0 0 2 and 0 0 0 3. A simple two router ospf network.
Ospf is an open standards link state routing protocol used to exchange routing information between devices dynamically. The example script shows the commands used to configure a sun netra cp3240 switch as the inter area router in the diagram by enabling ospf on port 0 2 in area 0 0 0 2 and port 0 3 in area 0 0 0 3. Learn ospf configuration commands ospf show commands ospf network configuration process id network id wild card mask and area number and ospf routing in detail. Set up your network as usual.
Use this procedure as a quick configuration guide. This document uses this network setup. Ospf is an interior gateway protocol igp it is widely used in large enterprise networks. This tutorial explains how to configure ospf routing protocol step by step with practical example in packet tracer.
List of terms term definition acl access control list lsa. Configure ospf on a multi access network configure ospf priority understand the ospf election process document the ospf configuration scenarios in this lab activity there are two separate scenarios. Example network consists of 3 routers connected together within 10 10 1 0 24 network and each router has also one additional attached network. Configuring an inter area router.
Ensure that the routing protocol ospf or is is works correctly. The system requires that traffic from router 5 r5 to r1 10 1 1 1 always passes through r3. In the first scenario you will learn how to configure the routing protocol ospf using the network shown in the topology diagram in scenario a. Let s walk through it.
Let s assume we have the following network. R1 will announce the 1 1 1 1 32 route and r2 will announce 2 2 2 2 32. In this network diagram a network ospf domain is used. Mpls needs a standard ip connection in order to establish forwarding bases.
Assume that r3 is a firewall in the network through which all of the traffic should be routed or that the link between r3 and r4 has more bandwidth than the link between r2 and r4. This document provides an example ospf network diagram and describes some of the main configuration parameters for ospf using the alliedware plus operating system. The routers are placed in area 0 and an ospf point to point link is configured between them. Here s an example of a network configuration that creates a very simple ospf network between two cisco routers.
