1. The class has agreed that the Washington School District will use Network 10.0.0.0, that the schools whose T1 lines connect to the Shaw Butte School will use Network 10.3.0.0 and that the Royal Palm School will use IP addresses in the range 10.3.41.0 to 10.3.60.254.

2. The autonomous network number for the school district will be 1.

3. The router commands sequence needed to implement IGRP on the Royal Palm School’s router is:

enable

config t

router igrp 1

4. Routers in this IGRP network will broadcast their route tables to their neighbor routers every 90 seconds. Each router begins by identifying its own directly connected networks. As the discovery process proceeds, routers discover the best path to destination networks based on information from each neighbor. Each of these other network entries in the routing table has an accumulated distance vector to show how far away that network is in the given direction. As the routing table grows, the bandwidth utilization for the routing updates increases.
