Configure this hidden command on the penultimate hop router (that is, R2 in the figure above ): Received in packets other than Database Description packets . Note: a FEC can contain multiple streams, but not a stream of a FEC , such as looking at a host Sina website, which is a stream and looking at Sina's video, which in turn is a stream, the two streams When Sina sends to a remote host, the path should be the same, so one FEC has multiple streams, but each stream does not belong to a separate FEC. *Aug 18 09:06:02.699: Layer 3 protocol ID: 2048 About 30.0 / 24 prefix, C allocates a label 23 , the mapping is transmitted to the B ; B local to 30.0 / 24 allocates a label 22 , the mapping is transmitted to the A .

" the routers connected to the multiaccess network (Ethernet) all have the same circuit ID . The circuit ID is a one-octet number that the router uses to uniquely identify the The term circuit ( Circuit ) corresponding to the interface . Because the NET address is used to identify the entire device, the Circuit ID is used to indicate a different interface. The router assigns a 1- byte Circuit ID to the interface as follows . (The router address and link information in the result of capturing the packet are respectively). System Id Type Interface IP Address State Holdtime Circuit Id Path option 10, type explicit test (Basis for Setup, path weight 20) *Aug 18 11:26:02.546: 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,ccna questions free, 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, 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.
