cisco ccnp 300-115 questions

A strange phenomenon has appeared. It seems that R4 does not reflect the route from R5 to R3 . Why? In theory, the RR will learn from non- client of IBGP neighbor to route reflection to their Client , but it is clear, in this experiment, R4 and did not learn from R5 route reflection to their Client . TCP / IP Volume II of this note contains TCPIP Routing Volume BGP almost all the content parts, and a detailed expansion AS_CONFED_SET A list of unordered AS numbers on a path to a specific destination , using the method with AS_SET Then, the situation is different for RSTP . After receiving the sub-optimal BPDU , C will immediately send back its own BPDU , so that B can understand the topology. This mechanism is very similar to BackboneFast . At the same time, the same OSPF route is learned from both processes and is used on a first come, first served basis. Therefore, if R3 first learns the route from R1 , it will naturally ignore the one that R2 re-releases. However, if the neighbor relationship between R1 and R3 is already obtained in R3 B Mode To confirm, the bridge responsible for notifying the topology change will continue to send TCN BPDUs before the bridge confirms the TCN . Next, the designated bridge will generate another TCN for its own root port , and the process is sent all the way to root . Neighbor 5.5.5.5 ebgp-multihop 3 Neighbor 3.3.3.3 route-map WT1 in neighbor 5.5.5.5 route-map WT2 in DHCP overview DUAL AS Router(config)# router ospf 1 10.1.23.3 from 10.1.23.3 (3.3.3.3) Detect the reachability of the next hop, the default is off The above command only re-advertises OSPF internal routes and E1 routes into BGP. [Experiment 7 ] There are subnet routes (no match); there are default routes OSPF multicast packets are flooded on the LAN . This is one of the most common applications of the passive-interface feature. Note that different routing protocols operate differently on the passive-interface . Vlans in spanning tree forwarding state and not pruned 300 {100,200}, (aggregated by 300 3.3.3.3) Extended ACL AS_CONFED_SET A list of unordered AS numbers on a path to a specific destination , using the method with AS_SET Network 4.4.4.4 0.0.0.0 area 0 Match ip route-source When the packet enters the router,cisco ccnp 300-115 questions, the router strips the Layer 2 information and then looks up the destination IP address in the CEF table for forwarding. The result of the forwarding decision will point to a neighboring entry in the adjacency list, in which the second layer of character letters that need to be rewritten can be found. Set local-preference set weight If you configure the following, then the COST comparison will exceed the weight and become the most preferred comparison rule. / / View the routing flip situation Configuration example 58 LACP mode: !! Take the default route Configure the Port-Security penalty mechanism Path The router goes to update the route of 3.0.0.0 When the RR reflects the route from the client to the non-customer, it also appends its cluster ID to the CLUSTER_LIST , and if the CLUSTER_LIST is empty, it creates one. If the route reflector finds that its local cluster ID appears in the CLUSTER_LIST of the route it received , then it knows that a loop has occurred and ignores the route. The CLUSTER_LIST attribute is only used for RR anti-rings.
