(3) WAN Logical Topology, including IP Addressing Scheme

Logical WAN Topology:

Note: all these images are derived from a master flash file - click "See it all working together" on the menu frame

Shows the functionality of the WAN.

Shows how WAN services have been assigned:

WAN-to-site = PPP (plus a dial up ISDN line for emergency access)
WAN core-toWAN core = PPP
WAN-to-Internet connections = Frame Relay
Community school-to-Shaw Buttes = dial up ISDN

Shows how subnets are assinged in the WAN.

List of Interconnections:

33 x T1 connections between each school & WAN core
33 x emergency dial-up ISDN lines (via phone lines) from each school to the nearest regional Hub
1 x permanant dial-up ISDN connection via phone lines from the community school to Shaw Butte
12 x T1 connections between the 3 regional Hubs of the WAN core
- another 12 x T1 redundant links have been proposed.
several short lengths of gigabit ethernet (CAT 5) to connect the DataCenter router to the Firewall router, and all of the servers (E-mail, DNS, DHCP & web server) on the public network to the Firewall router.
{note: this list of media does not include the media necessary for Shaw Butte school - just the media necessary to form the WAN core and public network}

Traffic Model

Shows how our WAN fits into the two-layer hierarchial model & gives insight into how traffic flow will work.

ConfigMaker:

An attempt was made to implement the WAN setup above in ConfigMaker, but due to ConfigMaker's limitations (expecially regarding lack of router models) the result was futile and not worth including.
