Overview EIGRPv6 uses the Diffusing Update Algorithm (DUAL) to: Calculate the Distances of routes from the source network to destination network. Inject loop-free routes into the EIGRPv6 topology table. Select the optimal route to a destination network from the topology table and injects it into the IPv6 routing table. (Sub-optimal routes remain in the topology…
A properly designed EIGRPv6 domain is easy to configure, converges quickly and if there is a change in the topology it can rapidly re-converge. This lesson provides a brief summary of some of the basic concepts EIGRPv6. The purpose is to provide a high-level overview. Many of the topics introduced here will be described in…

This lesson includes some Pro Tips and best practices to help you quickly identify and correct common OSPFv3 troubleshooting issues.
Overview EIGRPv6 Neighbors share route information that exists in their EIGRPv6 domain. Neighborships can form with devices that share a common link. For IPv6 neighbors, EIGRPv6 must be used. The formation of neighbors in EIGRPv6 is simple. With that said, there are differences in the way neighbors will form depending on the topology and configuration….

Overview In this lesson, we’ll configure and verify OSPFv3 Authentication and Encryption. OSPFv3 doesn’t have any “built in” mechanisms for Authentication or Encryption. It uses IPv6’s Internet Protocol Security (IPSec). OSPFv3 Authentication and Encryption can be configured on links: Per area Per interface A combination of per area and per interface IPSec offers two encapsulation types:…
