Ipv6 unicast-routing ( Routing Table ) , the routing table is loaded with routing entries ( routes ) learned by the router . The routing entries are composed of routing prefixes (destinations associated with routes), routing information sources, outgoing interfaces, or next hop IPs . The router obtains routing entries and maintains its own routing table in a static or dynamic manner. ICMPv6 is one of the basic protocols of IPv6 . Protocol number 58 , which is in the "Next Header" field of the IPv6 header. Address-family ipv4 Prefix E IPV6 header improvement R2(config)# router ospf 1 ? The vocation of the router is to maintain the routing table and use the routing table for data forwarding. The routing table contains routing entries or routing entries learned through various channels. The simplest and most straightforward method is to use static manual configuration to create routing entries for the router. This method is the most direct and controllable. The highest, the most simple configuration. In a small network, there seems to be no problem with static routing on the whole network. However, in a large network, if you use static routes purely, the workload is very large, not only the workload is large, but another more important defect is Static routes cannot be adjusted according to changes in network topology. Therefore, in large-scale networks,ccna training, we often use static + dynamic routing protocols to complete route deployment.
