A1: Using secondary IP addresses, a subnet of 192.168.5.0 must be added to the Ethernet interfaces of RTE and RTF to connect the noncontiguous subnets of those routers' Token Ring interfaces. The IGRP configurations are:

RTA

router igrp 50 network 192.168.2.0

RTB

router igrp 50 network 192.168.2.0

RTC

router igrp 50 network 192.168.2.0 network 192.168.3.0

RTD

router igrp 50 network 192.168.3.0 network 192.168.4.0

RTE

router igrp 50 network 192.168.4.0 network 192.168.5.0

RTF

router igrp 50 network 192.168.4.0 network 192.168.5.0
A2: The minimum bandwidth of the route is that of RTD's Ethernet interface. The total metric is the sum of this bandwidth and the delays of each interface:

1000 + 10 + 7 + 100 + 63 = 1180

A3: The minimum bandwidth ...
