Src 1.1.1.1, Dst 5.5.5.5, Tun_Id 0, Tun_Instance 9 RSVP Path Info: Keeping priority indicates how much weight a tunnel has, so that it can be preserved in the link; Basic Experiment 2 ( IS-IS ) Mpls ldp router-id loopback0 mpls label range 300 399 interface fast0/0 75000 R4 configuration is as follows LDP discovery sources: OSPF Router with ID (2.2.2.2) (Process ID 1) Router Link States (Area 0) OSI has established standards for two network protocols for routing: ES-IS and IS-IS : * 10.1.123.2, from 2.2.2.2, via FastEthernet0/0 Overview Fspec: ave rate=2000 kbits, burst=1000 bytes, peak rate=2000 kbits History: All routers in the LAN advertise their own connectivity to the pseudonodes in their LSPs (the adjacency relationship between themselves and the pseudonodes) ! 5135 ! *Aug 18 11:31:44.598: Label subobject: Flags 0x1, C-Type 1, Label 0 Above we can see the reservable bandwidth of all tunnel priorities. Now let's modify the reservable bandwidth of the tunnel with priority 6 . Global Pool BW Unreserved: End system adjacency routing Overview Then, finally, the data is introduced into the established tunnel . In fact, after creating a TE tunnel on R1 ,ccna exam simulation questions, a local tunnel is in it. !! Interface priority for electing DIS RFC 3567 R3#show ip cef exact-route 10.1.35.5 1.1.1.1 Use of OSI IS-IS for Routing in TCP/IP and Dual Environments 10.1.23.0/24 Mpls traffic-eng tunnels mpls ip Mpls traffic-eng tunnels mpls label range 300 399 The previous experiment used IBGP to establish IBGP adjacency on R1 and R4 to help you understand the MPLS environment. Experimental phenomena The above is the debug information under normal circumstances . (See Why is CEF remember?), Was found to give the packet label press, then press it on the label head, the label value 201 , then the next hop is B , which is sent to B . Then B receives the label package and finds that the label field in the label header is 201 , so I look at my own LFIB and find that the outgoing label of the 201 label is 301 and the next hop is C , so it replaces the 201 label with 301 , and then pays to C .
