Chapter 9

1: What algorithm does EIGRP use to decide which route is put into the routing table?
A1: Answer: Diffusing Update Algorithm (DUAL)
2: Besides the routing table, what other tables does EIGRP use in its operation?
A2: Answer: Neighbor table and topology table
3: What default metric values does EIGRP use?
A3: Answer: EIGRP uses bandwidth and delay as the default metrics in its calculations. It does not, by default, use MTU, load, or reliability. This means that EIGRP uses a calculation of 256(bandwidth × delay) in calculating its metric.
4: Why does EIGRP use protocol-dependent modules?
A4: Answer: EIGRP uses protocol-dependent modules to provide support for multiple routable protocols. Each protocol-dependent module handles the specific tasks ...
