As shown above, the position of the line is 16+4=20 , so we get the summary address: 192.168.0.0/20 , which is the most accurate summary address. Wherein 33: 33: FF: 01: 00: 0B is ipv6 destination address FF02 :: 1: FF01: B multicast mapping. The meaning of this command here is that only 1.1.1.0 is allowed to go out of the route redistributed from the RIP routing protocol (to OSPF , there is no direction, as long as the interface is running OSPF ) Data forwarding method Image Neighbor 4.4.4.4 update-source Loopback0 "Double-point bidirectional" routing re-release is a simple model that can often be used in large networks. For example, in a financial network, if a dynamic routing protocol is run between a secondary line and a branch router, then this model may be involved. The so-called two-point bidirectional refers to a node with two routes re-issued on the boundary of two routing domains, and the direction of re-distribution is bidirectional. For example,ccna practice exam, in the above figure, the secondary line has two aggregation routers for access to the following outlets or branch routers. Then the two routers are two-point. In addition, in order to make the routes of the entire network reachable, two-way routing re-distribution is deployed on the two routers, that is, OSPF is re-released to RIP , and RIP is also re-released to OSPF. .
