Dynamic routing allows for routers to keep up-to-date routing tables without constant manual updating by the system administrator. We will be utilizing Cisco's proprietary routing protocol, IGRP, in our network.
Default IGRP Timers
- Update: 90 Seconds
- Invalid: 270 Seconds
- Hold Down: 280 Seconds
- Flush: 600 Seconds
Our Timers
- Update: 1000 Seconds
- Invalid: 3000 Seconds
- Hold Down: 3030 Seconds
- Flush: 10000
Since our network will be relatively static with little changes, we felt larger numbers would be more efficient on bandwidth usage. Here is the command line:
Router(config)# router igrp 30878
Router(config-router)# network 10.0.0.0
Router(config-router)# timers basic 1000 3000 3030 10000
