No synchronization no auto-summary * i100.0.1.0/24 Next-hop , the next-hop is changed to the update source IP of R3 , which is the loopback interface IP. Commands 3.3.3.3 I can't ping because I found a subnet route after looking up the table at 172.16.1.1 . Therefore, the search is limited to the subnet route, and then the route is found to be mismatched. Therefore, the packet is discarded directly without going through the default route. . For example, if you go to a destination and there may be multiple equal-cost paths, you may actually use one of them when forwarding data. Use this command to see which interface is actually used for traffic forwarding. Passive-interface All VLANs except the following no VLANs Set native vlan on the trunk Vlan 10 Authentication Type At this time , OSPF routes are re-advertised to BGP on R11 , so that R12 can learn. After R12 learns the route, it finds that BGP attributes (including AS_PATH ) are lost. Because OSPF redistributed into BGP , the default does not automatically tag values are copied into the AS_PATH , the need to R11 on Origin IGP, metric 0, localpref 100,ccnp tshoot ine, valid, internal Since the AS_PATH attribute does not change within the AS (only when the route leaves the AS ), the AS inner loop has a horizontal splitting mechanism, and the route reflector actually relaxes the horizontal splitting principle . This will bring some hidden dangers to the loop. Therefore, the route reflector needs to use the following two attributes to prevent loops: FastEthernet0/0 Network 10.1.45.0 0.0.0.255 area 0 About Ethernet Enhanced Interior Gateway Routing Protocol (EIGRP) Open Shortest Path First (OSPF) The bandwidth of F0/0 port is 100M , and the bandwidth of S0/0 port is 1.544M . Except for the next time, it is just 1:60. ( 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. Neighbor table Configuring DAI logging There is indeed no atomic_aggregate . 3.3.3.3 (metric 65) from 3.3.3.3 (3.3.3.3) If the interface is trunk , set the trunk protocol type ? On R10 , the route is redistributed into OSPF . R11 learns 8.8.8.0 through OSPF . On R11 , the route is: Send Keepalive bag Network 10.1.34.0 0.0.0.255 area 0 3.3.3.3 ( metric 101 ) from 3.3.3.3 (3.3.3.3) No synchronization no auto-summary 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 , 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.
