As shown above, you want to replace the original area prefix 49.0001 with 49.0002 . To achieve this goal, configure an NSAP address for the new area prefix on A and B. Note that the SystemIDs of the two addresses must be the same. Then delete the areas of A and B in turn .

We open interface authentication between R1 and R2 : Both R3 and R5 must activate the forwarding adjacency feature. The IETF is working hard to develop a 3- step process for point-to-point links only by implementing a 3- step adjacency on the broadcast link. 129 Configure path protection on R2 and observe the phenomenon.

Each bit can represent an attribute of the link (such as whether it is encrypted or not) or a managed policy. There is no specific syntax for this 32bits . Each bit can be set to the latter without moving it. The network designer can think of specifying a specific meaning for a particular bit as needed . Ingress LSRs — Ingress LSRs receive a packet that is not labeled yet, insert a label (stack) in front of the packet, and send it on a data link. Network 10.1.12.1 0.0.0.0 area 0 Advanced features The path calculation of the MPLS TE tunnel requires relevant information to be performed. Then we need to use a link state routing protocol to flood the link information to all routers running TE in the network . After collecting the information, the TE router establishes its own MPLS TE Database .
