I have a need to change the Default gateway on about 635 machines which are not using DHCP. They want to use HSRP . I have the list of machines and their current settings. All I need to do is change the Default gateway to the new HSRP address scheme. It only consists of changing the last Octet since most of my machines are on Class C networks.Here is the break down
/26 Q1 .59/60 Q2 123/124 Q3 187/188 Q4 251/252
/25 1st half 123/124 2nd half 251/252
/24 .251 / .252
That would be ranges the machines would be in to use the HSRP standard. For example if the machine is has the following IP address 146.125.79.25 subnet 255.255.255.192 and It is in first Quad it would get 146.125.79.59 and 146.125.79.60 as the default gateways. Any suggestions Please help ...
