Hi,
Can someone please check below, to see if I am going in the right
direction.
I have 3 sites A B C
A wants 500 users. - should be a /23
B wants 2000 users - should be a /21
c unknown up to 200 - should be a /24
IP address range I have is as follows:-
10.225.200.0 to 10.225.219.255
I have worked the following:-
For A the range is 10.225.200.0 to 10.225.201.255 with a subnet mask of
255.255.254.0 or is it 255.255.255.0
It should be 255.255.254.0 for a /23
For B the range is 10.225.202.0-10.225.203.255 - 512 address
10.225.204.0-10.225.205.255 - 512 address
10.225.206.0-10.225.207.255 - 512 address
10.225.208.0-10.225.209.255 - 512 address
All with a subnet mask of 255.255.248.0.
For C the range is 10.225.209.0-255 to 10.225.210.0-255
subnet mask of 255.255.254.0
The bldg C address should be a /24 for 200 address's...you don't need a
/23 for 200 address's.
The 209 subnet is part of the /21 for area B....you should use
10.225.210.0 - 255 /24.
if all on single network will all these talk without any problems and I
still have 211 through to 219 free.
You will obviously need a router and have 3 networks...one for area A,
B, C...which would be 3 networks
Not one single network....
Another quick question was should these all respond across different
subnets even using OSPF or won't they.
They should respond and work across any routing protocol if the switches
and router are config'd correctly...
Thanks,
-DJ
