R1#show ip route 5.5.5.0 Pop tag This behavior will continue until the RESV message arrives at the head end router of the TE tunnel LSP . That is, after the request is made by the head end router, the label is advertised hop by hop from the tail router to the head end router. This shows that the TE tunnel uses the downstream passive DOD label distribution.

Therefore the NSAP address is at least 10 bytes. In the CISCO IOS in, the NSAP configured dotted 16 hexadecimal form. The AFI value of 49 can only be used locally, and is the reserved private address space defined by RFC1618 .

Since this experiment, the cost of R2 , R3, etc. ,current ccna exam, 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.
