Memory loss

[middee]

I have 2 cisco routers (3600 & 2500 series)

When i boot the routers, no probs. When i change the ip adress(of the ethernet interface) and put in some static ip routes and then 'reload', it simply forgets the ip adress and i have to start all over again.

I tried the 'write memory' command and 'save startup-config running config'. What could be the problem?

it sounds like your config register is set to 0x2142 , this setting ignores nvram , change it to 0x2102 and you should be good

You have tried 'save startup-config running config'. You need to save the running config to the startup config. Do a copy run start rather than a copy start run.

Well, i tried to put it to 0x2102, i thought this was the solution but it isnt. I set it, then reloaded. I putted in a ip adress and host name. Then a copy run AND copy start, also a write mem command, then it reloaded and it lost the memory, bye ip adress, bye host name.

Any other solutions?

in the rommon i changed it with a other command (o/r 0x2102 and now it works!
