EIGRP Summary
As you can see, EIGRP provides many advantages over both RIPv1 and RIPv2. Most significantly, it uses a much better metric, and it converges much more quickly than does RIP.
The biggest downside to EIGRP has traditionally been that EIGRP was a Cisco proprietary protocol. That is, to run EIGRP, you had to use Cisco products only. Interestingly, Cisco has published EIGRP as an informational RFC in 2013, so now other vendors could choose to add EIGRP support to their products. Over time, maybe this one negative about EIGRP will fade away.
The next topic introduces the final routing protocol for this chapter, OSPF, which has always been a public standard.
