Hi, It is possible, first telnet into the remote router, change its IP address to the new one, immediately you press the enter key after typing the IP address, you will be disconnected, so you must be prety sure that the IP address you typed is correct and no room for mistakes here, else too bad. then change the address of the router here to be on the same subnet with the remote routers IP address. Update all your static route entries to reflect the new changes. You reall have to be very care, If everything went on fine, after changing the IP address of the home router, re-connect and you will be well.
A safer alternative method is to use secondary IP addresses, eg Router1 is the remote router and Router2 is the home router and their initial serial IP addresses are: Router1(config-if)#IP Address 192.168.0.1 255.255.255.252 Router2(config-if)#IP Address 192.168.0.2 255.255.255.252 and you want to change them to the new IP address on subnet 172.16.0.4 255.255.255.252 Then first telnet into the remote router and do: Router1(config-if)#IP Address 172.16.0.5 255.255.255.252 secondary (If you forget the 'secondary' key word, your initial IP address would be replaced by this new one, putting the secondary keyword ensures that the remote serial interface have two IP addresses through which you can reach it) When that is done then on the second router Router2(config-if)#IP Address 172.16.0.6 255.255.255.252 secondary After this, logout test the telnet and pinging but this time use the secondary IP addresses, when you are comfortable that the new IP addresses are working fine. Telnet back into the remote router and do: Router1(config-if) No IP Address 192.168.0.1 255.255.255.252 do same to Router2(config-if)No IP Address 192.168.0.2 255.255.255.252 When you do this, the secondary IP addresses will automatically be revert back to be primary and your former primary would have gone for gone leaving you with your new set of IP Addresses running on both serial interfaces. my 0.2 Oletu ----- Original Message ----- From: Rajneesh Yadav To: Sent: Monday, December 10, 2001 5:27 AM Subject: how to change the serial port IP of remote end [7:28665] > Hi all, > > I want to change serial IP of my both the router one is placed in UK.so my > question is,can i change it remotely and how its possible.please if anyboby > can help me out. > > Regards > > Rajneesh _________________________________________________________ Do You Yahoo!?
