Scenario 8-3: Point-to-Point Configuration
Your job is to deploy a new network for an environmental research firm. Two main research
sites are in Boston and Atlanta; a T/1 line has been ordered between those two sites. The field
site in Alaska will need occasional access; ISDN BRI will be used. Another field site in the rain
forest of Podunk has a digital 56kbps link, but it has bursts of errors because parts of the line
are microwave.
The design criteria are listed following Figure 8-39, which shows the routers and links. Note
that some design criteria are contrived to force you to configure different features; these are
designated with an asterisk (*).

Scenario 8-3 Environmental Research Network
The design criteria are as follows:
·
Use three different WAN data link protocols.*
·
ISDN BRI will be used between Boston and Alaska. Boston's phone number is
1115551111; Alaska's is 2225552222.
·
Both ISDN BRIs are attached to DMS-100 switches.
·
Use IP subnets and IPX networks in Table 8-50. Allocate addresses as needed.
·
All IP user traffic is considered interesting for DDR.
·
IPX RIP and IP IGRP are the routing protocols of choice.
