6B is systemID + 1B of PSN ID Fa0/0 Network 10.1.45.4 0.0.0.0 area 0 mpls traffic-eng router-id loopback0 mpls traffic-eng area 0 75000 Conceptual introduction !! Re-release the local direct loopback 2.2.2.0/24 to level1 C 1.1.1.0 is directly connected, Loopback0 10.0.0.0/24 is subnetted, 2 subnets Hello interval: 5000 ms; Transport IP addr: 1.1.1.1 LDP Id: 2.2.2.2:0; no host route to transport addr Basic Tspec: ave rate=2000 kbits, burst=1000 bytes, peak rate=2000 kbits O 10.1.23.0 [110/2] via 10.1.12.2, 00:00:37, FastEthernet0/0 *Aug 18 09:06:02.699: SENDER_TSPEC type 2 length 36: NLPID: Tag or VC ! (Tunnel0) Destination: 4.4.4.4 10.1.45.4 10.1.45.5 697 Type Block Setting the priority and maintaining the priority all indicate whether a TE tunnel can preempt another TE tunnel by using the corresponding value . The lower the priority, the higher the importance. O 2.2.2.2 [110/2] via 10.1.12.2, 00:00:37, FastEthernet0/0 After receiving the label from the tail router, the penultimate hop router uses the label as the outbound label of the TE tunnel , and assigns a label to the tunnel and places the label in the label object in the RESV message. Send it to its own upstream router. !! Backup tunnel Network 10.1.34.4 0.0.0.0 area 0 IGP metric: 1 In this way, R2 will ignore the LDP hello packet received from the R1 on the interface , and then the LDP adjacency between R1-R2 will DOWN after a while. Type escape sequence to abort. Tracing the route to 5.5.5.5 0 kbits/sec Metric: 10 Using domain authentication,cisco ccna dumps 2016, IIH packet, CSNP , PSNP is not carrying authentication information, LSP is used to carry the authentication TLV . In PHP , we have seen the role of implicit null tags, of course, implicit null tags are not limited to PHP . It can also be used in messages with 2 , 3 or more tags in the tag stack . Using an implicit null label (in the LDP , the value is 3 ) on the outbound LSR will inform the penultimate hop router to remove the top label, and the labeled message passed to the outbound LSR will have one less label. In this case, the outbound LSR does not need to perform the search of two tags. Note that instead of using an implicit null tag, it is not necessary to pop all the tags in the tag stack, but to pop the top tag.
