I am really very much interested in Network Administration,and recently got a job in the same.We have remote locations having installed with new T1 lines, which means new circuits and new IP Space. The circuits have been delivered and are ready for us to schedule turn up with the carrier. The Cisco routers 1841 at those locations will need to be reconfigured for the new IP space associated with the circuits. Once this is complete we need to turn the service up. We are doing this remotely from the main office location. We will want to do this on a scheduled cutover with the vendor asap as the circuits havestarted billing.
IP information for the new connections has been provided for us with what we will need to swing the connections over to. Please find the attached IP information I was provided with. At the time of conversion we need to move the T1 service cable from 1 carriers demarc to the other.
As far as I know, I think I should just change the IP Address information and Subnet mask information in the Serial interface which is a T1 interface, and then change the static route information. I don't think I need to touch any other data in config file.
But the problem is when I try to change the config on the serial interface using the following I am loosing the connection with the router:
Enter configuration commands, one per line. End with CNTL/Z.
Router_1841(config-if)#ip address xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy
Thank you very much.
