RIP Deployment Scenario

OK, that’s enough of an IGP overview. There’s little doubt that the router-jockey readers of this book are champing at the bit to start routing some packets! Let’s demonstrate basic RIP configuration and operational mode commands that assist in troubleshooting a RIP operation in a Junos environment.

Figure 6-3 depicts the topology for the Cisco Systems/IOS to Juniper Networks/Junos RIP integration scenario. It shows the existing Beer-Co RIP network, which currently consists of two Cisco Systems 2600 series routers running IOS version 12.3(15b) and interconnected by a serial link. Beer-Co is expanding its widget operation and plans to add two additional locations. Despite the existing infrastructure, the CIO has opted to become a multivendor shop, and a decision has been made to deploy two Juniper Networks J-series routers. The existing (and planned) IP addressing is shown and contains a mix of subnetted class A and class C addresses (just to keep things interesting). Each router’s loopback address is also shown, along with a simulated customer network that is instantiated via a static route (labs commonly use a static route to represent a customer network for purposes of reducing equipment requirements). Note that the last digit of each router’s loopback address is tied numerically to that router’s simulated customer network to help ease requirements on the reader’s memory.

As a reminder, recall that in this lab, each router’s Fast Ethernet interface is tied ...
