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. Interface eth0/1 Interface OSPF supports the following network types: P2P , broadcast, NBMA , point-to-multipoint, and on-demand circuits Distribution mode : Label Allocation Remote binding: tsr: 2.2.2.2:0, tag: imp-null Cross-region TE Tunnel ( OSPF ) Type the IS : first 1 , 2 bits for indicating the type of router is L1router or L2router Ip address 4.4.4.4 255.255.255.255 A puts the data on the label 23 , goes to B , and ejects the label header to C ( PHP mechanism); C receives the IP packet to find the FIB table, and then presses the package 55 to D , D finally finds LFIB and Pop the label to drop the IP packet to E , and E forward the IP packet to the destination. Mpls ldp discovery targeted-hello accept from accept-ldp Redistribute isis ip level-2 into level-1 route-map test RSVP uses PATH and RESV messages to pass signaling in one path. The TE head end router sends a PATH message to the tail router. Wait for the message to view the adjacency. Next, the DIS election process begins .

For example, the tunnel interface is manually shut down .

It is mainly a newly added two TLVs ( Type-Length-Values ) supporting IPv6 routing information and a new NLPID ( Network Layer Protocol Identifier ). IS-IS is not like RIP and OSPF . These two protocols have separate versions of RIPng and OSPFv3 support IPv6 . 1bit Ip address 10.1.23.3 255.255.255.0 1.0.0.0/32 is subnetted, 1 subnets Used to uniquely identify an LSP and authentication source router 10.1.12.2 Remaing lifetime LSP lifetime before LSP ID LSP identity Sequence num LSP serial number IS-IS Level-1 LSP R1.00-00 =250000 bytes/sec !

When the source router receives the PSNP acknowledgement sent by the neighbor , it stops sending new LSPs to this neighbor . In the LAN , there is no clear PSNP confirmation. The lost LSP can be detected. If any of the LSP missing or expired, Router are to PSNP send a request form to request retransmission of the LSP .
