Implementing EIGRP for IPv6
FirstPublished: February 27, 2006
Last Updated: August 10, 2007
Customers can configure Enhanced Interior Gateway Routing Protocol (EIGRP) to route IPv6 prefixes.
EIGRP IPv4 runs overan IPv4 transport, communicates only with IPv4 peers, and advertises only IPv4
routes, and EIGRP for IPv6 follows the same model. EIGRP for IPv4 and EIGRP for IPv6 are configuredand managed separately. However, the configuration of EIGRP for IPv4 and IPv6 is similar and provides
operational familiarity and continuity.
