Correct/Incorrect configuration of CISCO Router 877

[alshahatit.awad@gmail.com]

Hello all,

I do not have much experience with configuring CISCO Routers, but I had to try configuring it.

Below is the output from Show Run command, please check below and let me know if anything is missing or if I need to adjust things in a correct way.

Hello,

I lose the entire configuration.

Thanks,

Hello,

sounds like a memory issue...

Have you tried what I suggested in a previous post ?

1. wr erase --> this will erase the content of the NVRAM

2. erase flash: --> this will erase all files on the flash card

3. format flash: --> this will reformat the flash card

Hello,

Yes, I have tried the below:

1. wr erase --> this will erase the content of the NVRAM

2. erase flash: --> this will erase all files on the flash card

3. format flash: --> this will reformat the flash card

Then wrote the configuration again, but same behaviour as after a day, everything disappear.

I have also tried the same configuration on a new functioning router with the same model, and the same issue occured again.
