Lesson 2

Static and Dynamic Routing

5-23

4. Click the RIP icon and, on the Action menu, click New Interface. The New Inter-

face For RIP Version 2 For Internet Protocol dialog box appears.

5. In the Interfaces list, select the interface that connects your computer to the LAN

and then click OK. A RIP Properties dialog box for your selected interface appears.

In the General tab, you can specify whether the RIP outgoing messages your

server transmits should use the RIP version 1 or version 2 packet format, broad-

casts or multicasts, or no transmissions at all. You can also specify whether the

server should process incoming RIP messages that use the version 1 format, ver-

sion 2, or both.

6. Click the Advanced tab and then change the Periodic Announcement Interval

(Seconds) setting to 300 seconds.

The Periodic Announcement Interval (Seconds) setting is the frequency at which

the router transmits its RIP messages. In a stable network where configuration

changes and communications failures are rare, you can safely increase this setting

to reduce the amount of broadcast traffic RIP generates.

7. Change the Time Before Routes Expire (Seconds) setting to 1800 and the Time

Before Route Is Removed (Seconds) setting to 1200.

If you increase the Periodic Announcement Interval (Seconds) value on all the RIP

servers on your network, you must increase these two settings as well so that the

router does not purge the routing table too quickly of information from RIP.

8. Click OK. The interface you selected appears in the details pane, along with sta-

tistical indicators displaying the number of RIP messages the server transmits and

receives.

9. Leave the Routing And Remote Access console open for the next exercise.

Exercise 3: Disabling Routing and Remote Access

In this procedure, you disable RRAS, removing the configuration you just created. This

leaves RRAS in its original state, so that you can create different configurations later in

this chapter.

1. Click SERVER01 (local) and, on the Action menu, click Disable Routing And

Remote Access. A Routing And Remote Access message box appears, warning you

that you are disabling the router.

2. Click Yes. The Routing and Remote Access service is stopped, and the subhead-

ings beneath the SERVER01 (local) icon disappear.

3. Close the Routing And Remote Access console.
