EIGRP enjoys many new technologies, each of which represents an improvement in operating efficiency, rapidity of convergence, or feature/functionality relative to IGRP and other routing protocols. These technologies fall into one of the following four categories:
Neighbor discovery and recovery
Reliable Transport Protocol
DUAL finite-state machine
In addition to these categories of technological improvements, EIGRP was also treated to some other substantial enhancements relative to IGRP. These enhancements may defy easy categorization, but were needed to keep pace with the ongoing evolution of IP as well as other routing protocols. EIGRP enhances the security of a network, for example, by permitting ...
