TOPIC: CCNA Lab Question

CCNA Lab Question 16 years 6 months ago #3544

I am a CCNA wannabe (In CCNA Academy) who just got two routers and a Serial Back to Back cable for my Lab setup.

The problem that I am having is when I make configuration changes, they are not being saved when I reboot the router. I do run the following:

Router_A#copy running-config startup-config

When I do a sh ver, my register setting is 0x2142. So that means that it is pointing to NVRAM right?

What is my problem?
I have 2-2500 Cisco routers. Please help me. Thanks.

Hi there Technosavy,

Your problem is the configuration register! You have set it tp 0x2142 which tells the router to actually ignore the startup-config file while booting!

Fixing the problem is easy, just follow these steps:

1) Log on to your router and enter global configuration mode

2) Enter the following command:

Router(config)# config-register 0x2102

Router(config)# end

Router# reload

When the router reboots, you will see it loading you startup-config file!

Let us know if you have any problems.
