EIGRP, a versatile routing protocol supporting IP, IPX, and Appletalk, gave rise to the idea of extending its TLV capabilities to accommodate IPv6 e to its widespread adoption. Starting with IOS 12.4(6)T, EIGRPv6 integration has been initiated.

Thanks to EIGRP's molar design, as depicted, the implementation of IPv6 within EIGRP is straightforward - a new protocol mole is required. It is seamlessly integrated into the IPv6 stack, maintaining the same protocol identifier of 88. However, three additional TLVs are introced:

Similar to IPv4, EIGRPv6 retains the use of a 32-bit RouterID, employs the same metric calculation, and supports MD5 encryption. Unlike OSPFv3, which utilizes IPSec, IPSec authentication is not currently available in EIGRPv6. Cisco plans to introce this feature in future releases.

One significant difference between EIGRPv6 and its predecessor is the use of link-local addresses as source and destination addresses in Hello messages, targeted at the multicast address FF02::A. This allows neighbors to establish relationships without needing a shared prefix, a characteristic absent in IPv6's default behavior.

Another crucial distinction is that IPv6, with its support for multiple address prefixes on a single link, does not employ the concept of horizontal segmentation, unlike EIGRP.
