R1 and R2 run RIP ; R2 and R3 establish OSPF neighbor relationships. In the initialization case, there are four entries in the routing table of R2 , as shown in the figure above, and there are only two entries in the routing table of R1 , that is, two direct links. So now, we do the re-release action on R2 , and redistribute the OSPF route to RIP , then the configuration is as follows: After the basic configuration is complete, take a look: Netflow switching Strange phenomenon: In the BGP table of R5 , there are only two routes advertised by R2 , and the 100.0 route from R3 is not passed to R5 via R4 . In other words, we expect that AS345 will have redundancy to 100.0 network. Remaining path (through R1 , BGP table on R2 : 200 Diameter refers to a diameter value, the default is 7 . This value is related to the STP timer. If the different diameter values ​​are configured, the switch will automatically adjust the hello and max age timers. This command is usually configured on the root , so that the timer value is passed to other switches through bpdu . r >i1.1.1.0/24 The configuration of R5 is as follows: At the time, it is already " 200 i ", so doing prepend can only be inserted in front of 200 i , please pay attention to the difference from the previous one. (2) Declare the loop port 1.1.1.1224 The NEXT_HOP summary route is 0.0.0.0 (because the summary route is generated locally) Matches the preceding character 0 times or 1 occurrences When the link between R1 and R3 fails, the same network will still have problems. Because R2 re-releases the locally configured static summary route into the Ip route 172.16.1.0 255.255.255.0 192.168.12.1 Finally note: Sw(config-vlan)#private-vlan community Bridge ID to be unique bridge ID said earlier, is a priority and MAC constitute an address in the MAC address reduction scheme, all spanning trees of the same switch ID , the MAC address uses its own switch CPU 's MAC , At the same time , the priority of 16bits is expanded to become the system ID of 4bits priority + 12bits , and the system ID is used to identify different VLANs . In CISCO IOS ,ccnp route ospf lab, this system ID uses the VLAN.
