EIGRP RFC 7868
Finally, informational EIGRP RFC 7868 has been published.It is not anymore Cisco’s EIGRP, it is an open standard. Without a most critical feature of EIGRP,can we really say that? Why Cisco doesn’t share the most important feature which can help in large scale EIGRP design although industry has been asking from them for a long time ?
EIGRP RFC 7868 specifies EIGRP Dual Algorithm, EIGRP Packets such as Update, Query and Reply, EIGRP Operation, and EIGRP Metrics (K1,K2,….K6).
And since EIGP is RFC anymore, other vendors can legally implement EIGRP. There was couple of open source EIGRP implementations already,but with the RFC status, seeing new implementations among the big vendors would not be a big deal.
In addition to EIGRP packet types and metric values, there are a couple of important things to understand about EIGRP.
Among them is how EIGRP, as a distance vector protocol, calculates a best path and advertise it to the neighbors.
Understanding what is EIGRP successor, EIGRP feasible successor, EIGRP feasibility condition, metric values and usage in real life deployments is among the most important parameters in EIGRP that should be properly understood.
EIGRP RFC is an 80-page document, which provides detailed Continue reading
