Using the Topology shown, we will configure the Routing Protocol OSPFv3:
Once again, we will be using the same topology, since we already have the IPv6 addresses in place and we know we have connectivity throughout the network. We are simply going to change the routing protocol to OSPF.
This presents an interesting situation, not only for your certification but for real-world scenarios as well. Let's analyze this more closely. We already have EIGRP for IPv6 working fine, but your boss wants you to use OSPFv3, so what do you do?, so what is the issue? The issue is the administrative distance (AD) of the routing protocols. EIGRP has an AD of 90, while OSPF has an AD of 110, so that means if we don't change the AD of OSPF to something lower than EIGRP, OSPF will never make it to the routing table. Removing EIGRP completely before you have another routing...
