I will be setting up a cisco site to site vpn for the first time. I will attempt at creating two sites connecting to the main office. In order for the site to site vpn to work among site, I will need to have a different subnet per tunner.
My idea is the following.1st site.
Address: 172.16.0.1 Netmask: 255.255.255.0 Wildcard: 0.0.0.255
= 254 hosts
Address: 172.16.0.2 Netmask: 255.255.255.128 Wildcard: 0.0.0.127
= 126 hosts
Address: 172.16.0.3 Netmask: 255.255.255.192 = 26 Wildcard: 0.0.0.63 Hosts/Net: 62
Am I correct to say that this setup will meet cisco requirement for separate subnet masks? even although the ip addressing is similar?
I went from a site with 254 hosts to site 2 with 126 down to site 3 with 62 hosts. Each site has a distintive subnet mask. I would like to keep each site ip addressing similar as its easy to remenber. Site1 ends with .1 site two with .2 and site 3 with .3
and please pardon my newbiness. I am trying to understand it all as I go.
