* Support for [[load balancing (computing)|load balancing]] on parallel links between sites.
* The ability to use different authentication passwords at different times.
* [[MD5]] and [[SHA-2]] authentication between two routers.
* Sends topology changes, rather than sending the entire routing table when a route is changed.
* Periodically checks if a route is available, and propagates routing changes to neighboring routers if any changes have occurred.
* Runs separate [[routing]] processes for [[Internet Protocol]] (IP), [[IPv6]], [[IPX]] and [[AppleTalk]], through the use of [[protocol-dependent module]]s (PDMs).
* Backwards compatibility with the IGRP routing protocols.<ref name=intro>[http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a0080093f07.shtml Introduction to EIGRP]. Cisco. Retrieved on 2014-05-30.</ref>
