Deciding what network topology to use when putting a CCNA lab is a basic part of standard CCNA training.
Basically, routers and switches are necessary in setting up CCNA labs. Fewer routers and switches should not cause panic. It is a test on how the lab designer can maximize its availability and utilization.
An access server with octal cable is necessary to install in any CCNA lab to connect AS (autonomous system – collected IPs) to the rest of devices the designer chose to utilize. Furthermore, the accessibility of the frame
relay switch (4500 router) to configuration and troubleshooting is fundamental for the designer to succeed in the CNNA exam.
Subsequently, routers (two 3620s) will locate on the 4500 router cloud, stopping at the serial interface with two 2503s as well.
After configuring the frame relay switch, it should be connected to the rest of routers by means of a DTE/DCE cable. The two 2503s routers ought to be attached through their BRI interfaces with ISDN simulator. An ISDN
simulator allows routers to correspond with their connection by means of BRI interfaces (since Cisco routers cannot be directly connected via BRI interfaces.)
Enclosing a single Ethernet or AUI port at all routers is essential then connect them to any of the switches.
Switches ought to link to two crossover cables to allow trunk test, root bridge election, and VLANs. Two switches in a lab setup will increase the CNNA capabilities and testing with various subnets and VLANs can be
done as well.
You’ll need another DTE/DCE cable in utilizing bi-routers with non-operating serial ports. It should be attached directly with their serial ports. Remember to add loopback interface to each one of your routers.
Learning to set up lines between two straight-linked serial ports as well as troubleshooting are crucial CNNA skills.
