When the MPLS network is troubleshooting, it should follow from the control plane and the network plane to troubleshoot. Let's take a look at what two planes do. Above is the control plane, below is the network plane. From the forwarding plane is the network plane, there will only be two kinds of messages, inbound for the IP packet, and inbound for the MPLS tag packet, then the corresponding two messag

Before learning MPLS, you should know that MPLS has two modes of operation. 1, Frame mode--gt; in the third-level group header (such as IP packet header) before the tag to forward. 2.---gt; in the MPLS network composed of ATM LSR, MPLS is used to exchange Vpi/vci information in the control plane instead of using ATM

The code from chapter 7 of Intel assembly language programming (fifth edition) uses the AAA (ASCII adjust after addition) command to adjust the results after the ASCII addition.

Generally divided into: 1, 2, 3, 5, 7, of which 5 and 7 are particularly commonly used, the so-called AA battery is 5, and AAA battery is 7! Both AA and AAA indicate the battery model. For example: AA is what we call battery 5. The general size is 14mm in diameter and the height is 49mm; AAA is what we call battery 7. The general size is 11mm in diameter an

The principle of the protection of TE is already mentioned. Today's focus is to explain how the Frr-fast-reroute in Te Protection is configured, and how to look at the state. Before introducing the configuration, it is important to note that FRR fast rerouting is a protection mechanism. Imagine if the R2 to R6 is an ordinary IGP network. After the middle link down, what is the situation? It should be the first problem the router sends the LSA through the other interface and then reddening to

MPLS (Multi-propocol Label Switching) is a Multi-Protocol Label exchange.MPLS is a third-generation network architecture and a new generation of IP High-Speed Backbone Network Exchange Standard, proposed by IETF (Internet Engineering Task Force, Internet Engineering Task Group, led by Cisco, ascend, 3Com, and other network equipment manufacturers.MPLS is an integrated IP over ATM technology. It combines routing functions on Frame Relay and ATM switch,
