ccna simulation questions

AutoRoute: enabled auto-bw: disabled NSEL is 00 ( 1B from the right ) The system ID is 0000.0c00.1111 The area ID is 39.0f01.0002 204 Look at the example above: A is in the area 49.0001 , B is in 49.0002 , because they are in different areas, so they become Level 2 adjacencies. Maintain adjacencies in the region at the same time. If A is configured: This will directly cause R1 to select the nearest exit from R2 and R3 , and generate a default route to point to this exit. Since this experiment, the cost of R2 , R3, etc. , there are two defaults in R1 's routing table. Route load balancing. This default, automatic mechanism is a benefit for the level1 area because it can reduce the routing table and provide a way to go out,ccna simulation questions, but it also poses a problem, for example, if R2 or R3 is connected to the backbone . If the link DOWN is gone, will R1 still stupidly throw the packet to R2 or R3 ? Fortunately, in the new CISCO IOS , IS-IS is optimized: under normal circumstances, R2 and R3 will flood the 49.0001 area.
