List of commands required to change static IP address on a Cisco 800 Series Router
Hi
I need to change the static IP address on a cisco 800 Series router after the changing of a static IP. The router in question is the head end of a hardware VPN tunnel set up (between 2 x Cisco 800 series routers). I have been through the configuration and taken some snippets of the code where I can find the associated (old) Static IP. I just want ot double check I have everything right before having a crack at it. new address is 120.160.65.46
Code Snippets:
1.
ip host remoteoffice 203.45.189.100
2.
crypto isakmp key SDSDF#gS*DFH address 203.45.189.100
3.
crypto map GRETUNNELS 30 ipsec-isakmp
set peer 203.45.189.100
set transform-set ENCRYPT-GRE
match address REMOTEOFFICE-TUNNEL
4.
interface Tunnel2
description HEADOFFICE TO REMOTEOFFICE TUNNEL
ip address 192.168.254.9 255.255.255.252
tunnel source FastEthernet4
tunnel destination 203.45.189.100
crypto map GRETUNNELS
5.
ip access-list extended REMOTEOFFICE-TUNNEL
remark IDENTIFY VPN TRAFFIC TO REMOTEOFFICE
permit gre host 111.253.122.92 host 203.45.189.100
remark IDENTIFY VPN TRAFFIC TO REMOTEOFFICE
If you could provide the commands in order it would be appreciated

Commands worked exactly as shown. Was onsite at the remote office to complete commands and then was able to remote into the head office (using a wireless broadband connection) to complete the required changes at that end. Thanks for the help.
Routers
A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

i would suggest you use the command
reload in 30
or
reload at 18:00
on all routers
this will allow you to get the configs wrong and have another go when the routers reboot.
