- The best way that I've found to "visualise" this problem (and the
- solution to it) is to work along the following lines:
-
- A Class "C" Subnet maps directly to one AppleTalk (IPTalk) network,
-
- A Class B Subnet contains 254 (255? 256?) Class C Subnets,
-
- Therefore a Class B Subnet potentially contains 254 AppleTalk
- networks. All you have to do is to name them (i.e. allocate
- network numbers for each IP address that has the third octet
- different).
-
- After having "named" them on your whiteboard, transfer the
- information (the AppleTalk network number, IP subnet number and zone
- name) to your atalkatab file and reboot the gateways.
