Packet tracer 5.2 Lab (11) Comprehensive router routing configuration

I. Lab Objectives

• Master the configuration of Integrated routes;
• View the routes generated by route redistribution;
• Familiar with Wan cable connection methods;

Ii. Lab background

Assume that a company connects to the egress router R1 through a layer-3 switch, and router R1 is connected to another router R2. Layer 3 and R1 run the r12002 routing protocol, while R1 and R2 run the OSPF routing protocol. Now, we need to make proper configuration to implement communication between the company's internal host and the company's external host.

Iii. Technical Principles

To support this device to run multiple Routing Protocol processes, the system software provides the routing information from one routing process to another. For example, you can re-distribute the routes in the OSPF routing domain and then advertise the routes in the rip routing domain to the OSPF routing domain. The redistribution of routes can be performed between all IP routing protocols.

To distribute routes from one route domain to another and control route redistribution, run the following command in route Process configuration mode:

Redistribute Protocol [metric] [metric-type] [Match internal | external type | NSSA-external type] [tag] [route-map route-Map-name] [subnets]

Iv. Experiment steps

Lab Topology

1. Direct Connection is used between the PC and the vswitch, and cross-line connection is used between the PC and the route, route, and route.

2. divide two VLANs on the layer-3 to run the ripv2 protocol; r2 to run the OSPF protocol;

3. Configure the r12002 routing protocol on the left of router R1 and the OSPF protocol on the right;

4. introduce external routes in the R1 router process for Route redistribution;

5. Set the default gateways of the pC1 and PC2 hosts to the IP addresses of the interfaces with the directly connected network devices;

6. Verify that the pC1 and PC2 hosts can communicate with each other;
