Chapter 3, EIGRP.

Started reading about the inner workings of EIGRP today. EIGRP is an improved distance vector protocol provided by Cisco themselves. It is an improved distance vector protocol, because it passes updates directly to its neighbours. It is more advanced than traditional distance vector protocols, because it supports VLSM and it does not use periodic updates. It uses hello packets like link-state protocols.

1st reading done includes:

• EIGRP packet types.
• DUAL selection + selection examples.
• Neighbour establishments.
• Successor(s) + feasible Successor(s).
• Advertised distance + feasible distance.
• Metric calculations.
