The initial situation is the same as above. Let's take a look at redistributing OSPF routes into EIGRP AS 100. The configuration is of course still carried out on R2 . s> 172.16.11.0/24 EBGP neighbors must be directly connected to establish an EBGP session. but In 802.1D , the TYPE field uses only the highest and lowest bits to indicate TC and TC acknowledgment, and RSTP extends this field: Vlans allowed and active in management domain Next Hop Verify again, instead of detailed routing, use a summary route of ip route 10.0.0.0 255.0.0.0 , the next hop is R3 , the effect is the same as above, also take R3 . Therefore, as long as it is not the default route, as long as there is such a matching route in the routing table, the route is taken preferentially, and the route-map is taken without the route . First of all, the route-map is a very important tool, and it is used in a wide range. When defining a route-map , we use the route-map keyword to associate a custom parameter, such as test . A route-map list by the test string unified representation, you may be in one route-map define a plurality of sequences, a sequence number to a decimal representation, such as the figure above, 10 , * i Ge ge-value Match ad , abcd , aaabcd, etc. Distance vector routing protocol 28 bootPC: 67 (client port number); bootPS : 68 (server port number) Route-map test permit 10 set community ? RIPv1 This property may not be supported, but even if it is not supported, the route containing the property should be accepted and passed 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 . RSTP Active is local Then observe the BGP table on R4 : Automatic summary Metric 0.0.0.255 will not work. The maximum number of secure MAC addresses allowed by default is 1 1 32 bits 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 . Routing. So go to both network segments and go to R1 . So if we want to go to 11.11.11.0 and take R3 , so that these two destinations can be diverted? We can choose to route the source from 10.1.12.1 in the EIGRP process of R2 . We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows Network 20.20.20.0 mask 255.255.255.0 Access-list 1 permit 192.168.1.0 There is no match to a or c or t the end of the content SW1(config)# interface fast0/23 Match ip address prefix-list 30 set community 300:30 Therefore, we still need to keep the AS_PATH of its details on the summary route. As for the order of the AS number in the AS_PATH of the reserved detailed route , it is not important, because we only need the AS number for the purpose of anti-ring. It is. Therefore , the summary route generated by R3 actually carries two AS_PATH types, one is AS_Seq , the value is 300 , the other type is AS_set ,how to master ccnp switch free download, contains two AS numbers of {100,200} , and is unordered. So the AS_PATH received on R4 is 300 (100,200} combined . It is worth noting that the AS number in this bracket is only counted as one hop when performing the AS_PATH calculation. For the verification of this point, please see the section on routing rules.
