In the Level1 link state database. Each zone in the IS-IS domain has a unique Level1 link state database. The shortest path is calculated by the SPF algorithm. 3.3.3.3/32 Router isis LSP various types of TLV For IP applications , 1 byte defines AFI in the NSAP address , at least 2 bytes defines the actual area information, 6 bytes defines the system ID and !!

In fact, an LSP is a path when a packet traverses an MPLS network or a part of an MPLS network. 202 Router(config)#mpls traffic-eng tunnels The Level 2 LSP contains all the prefix information that may be reached in IS-IS . Level1 LSP is only used in the local area. The R2 re-released 2.2.2.0 external route is still there; the inter-area route is gone, except for a R2 local direct connection of 24.0 ; in addition, R1 still does not use R2 as the next hop of the default route. 10.1.34.4 Show isis spf-log LSP Seq Num LSP Checksum LSP Holdtime Bytes tag switched The external route is not carried in the LSP . Experimental configuration Experiment 1 Link[0 ]:Nbr IGP Id: 10.1.12.2, nbr_node_id:8, gen:47 frag_id 0, Intf Address:10.1.12.1 Mpls traffic-eng tunnels ip rsvp bandwidth After the MPLS LDP-IGP synchronization is activated on an interface , the IGP will advertise the metric of the link to the maximum until the synchronization is complete or the LDP session is successfully established on the interface. In OSPF , the metric is up to 65535 . In this way, it can be guaranteed that no path will pass through the interface when LDP is in the disconnected state.
