Integrated IS-IS ( IS-IS ) enables the IS-IS protocol to propagate routing information for protocols other than CLNP . 0x3B83 Receives packets from other L2 routers in the area and forwards the packets to the L2 routers of other areas according to the destination address (or to the L2 router of the same area ). Receive packets from L2 routers in other areas and forward the packets according to the destination address. TLV135 : Extended IP Rechability IS-IS link type This NSAP address is still a bit longer, and it is inconvenient to use. The SystemID is mainly used to identify several attributes, such as adjacency information, LSP identifier in IS-IS database, etc. In most cases, We are more suitable for symbols that have literal meanings, such as R1 and R2 ,mcse ccna, rather than a string of numbers. So CISCO IOS provides us with a very good way: the mapping of the router hostname to the NSAP address. Essentially the mapping of hostname to SystemID . There are two methods of static mapping and dynamic mapping.
