LDP discovery sources: Let's look at the picture. If R1 to R6 want to establish a TE tunnel , which is the optimal path, and the bandwidth requirement is 30Mbps , what is the calculation process? First of all, thanks to the flooding of link state information in the zone, " OSPF or IS-IS for MPLS TE extensions ", Interface fa0/0 mpls ip Routing information diffusion and database synchronization Remote binding: tsr: 2.2.2.2:0, tag: imp-null remote binding: tsr: 3.3.3.3:0 , tag: 301 The maximum number of regional addresses configured by a single router must be the same as that of neighboring neighbors. By default, CISCO IOS routers support the maximum number. Protocol overview IS-IS routers belong to only one specific area Interface Loopback0 The configuration of R1 is as follows: PDU length : the length of the entire PDU ,ccna training in india, including the header The label is incorrect. This situation only occurs when the IGP is OSPF . Because if the loopback is used as the router-id of the ldp and it is not 32 -bit, OSPF will automatically issue the 32 -bit loopback address. Causes the label to be assigned an error.

We found that R2 can learn to R1 of the Loopback , R3 of the Loopback , and R3 directly connected interface routing of 34.0 , which is due to R4 pass R3 and R2 passed R3 of LSP did not carry the authentication information, then these LSPs to R3 after, R3 is definitely an error, so R3 will not flood the original LSP sent by R4 to R2 , and 3 will not flood the original LSP sent by R2 to R4 . However, R3 sends out its own LSP.There are R3 directly connected network segments 3.3.3.0 and 10.1.23.0 , 10.1.34.0 . These LSPs are flooded to R2 and R4 . Although LSPs carry TLV information for authentication , R2 and R4 do not open domain. Certification, so they directly ignore the certification information and then start reading LSP , which is the interpretation of the results of our experiments. Of course, if R2 and R4 are configured with domain-password but the password is different from other devices, then it goes without saying that directly discarding LSPs with different passwords will not be read at all.
