The identity of this circuit is assigned by the router that sent the Hello PDU and is unique on the interface of the router. At the other end of the point-to-point link , the local circuit ID in the Hello message may or may not be the same value. Outgoing tag or VC AutoRoute defect Label 3 implicit null label ! Mpls traffic-eng tunnels mpls label range 100 199 Based on the information in the link state database, the almost identical algorithm, the SPF algorithm, is used to calculate the optimal route.

Then if we configure: In the above figure, R1 , R2 , and R3 run OSPF , and the direct connection and loopback are announced . The loopback is addressed to xxxx/32 , and x is the device number. At the same time, all direct interfaces activate LDP .

When R1 goes to 1.0/24 and 2.0/24 , traffic will be sent to different tunnels on R1 . At this moment R1 is the head end of my tunnel , and R5 is the end. The tunnel can set bandwidth requirements so that my tunnel can make more scientific and reasonable routing in the network, not just using OSPF metric for routing. The calculation of the tunnel path is done on the R1, which is the tunnel first-end router. In order to enable the head-end router to calculate the tunnel path more reasonably (not only using metric , but also participating in the path with elements such as available bandwidth and link attributes. Computation),ccna classes online, we need to extend the link state routing protocol running in the network, in order to flood the information required for more path calculations, extended OSPF and IS-IS can accomplish this task.
