Here, because there is an OSPF interval , and OSPF does not know BGP , the BGP attributes will be lost during the re-release process . Both R1 and R2 inject 100.0.1.0 and 100.0.2.0 into BGP using network . In the above figure, if both ends of the PC belong to vlan10d , if the fa0/23 port of SW1 will vlan10remove off, then the PC will definitely not be able to communicate. External RIPv2 supports authentication by changing the field in the RIP message that should normally be the first route entry . In the single update message with authentication , the maximum number of route entries that can be carried is reduced to 24 . Precautions: Routers can learn routing entries in a variety of ways: static manual configuration, various dynamic routing protocols, and more. When the router learns two routes to the same destination from two different ways, the router compares the AD values ​​of the two routes ,sikandar ccnp switch workbook, that is, the management distance, preferably the route with a small AD value. If the AD values ​​are equal, for example, the same routing protocol, the metric value is further compared . Of course, this also involves the working mechanism problem of different routing protocols, which is specifically discussed for different routing protocols. As shown in the following figure, R3 and R1 run the RIP protocol, and R3 establishes adjacency relationship with R2 through OSPF . Therefore, R3 learns the route to the destination 1.1.1.0/24 from RIP and OSPF . The two routes use R1 and R2 as the next hop respectively. Then R3 finally chooses the OSPF route to be loaded into the routing table, which is to use R2 as the actual destination.
