Next, let's take a look at the details of these LSPs : Ip address 55.55.55.55 255.255.255.255 Res. Global BW: 75000 kbits/sec !! interface's maximum reservable bandwidth From the above figure, we can see that R1 and R4 act as L1 routers and only maintain the link state database of Level1 , and R2 and R3 are L1/L2. In front of the IP package. Then this 303 is actually the label assigned to the route of the next hop 10.1.15.0 of BGP route 5.5.5.5 . In other words, LDP does not assign labels to BGP routes, but assigns labels to the next hop (route) of BGP routes. Comprising one or more routers is configured on the source IP address, the CISCO IOS in A router can have up to 254 th Area ID . Of course, generally one router belongs to one area, and the situation of multiple areas may be used for merging, splitting or changing of areas (see below). !! Path error message sent by R2 to R1 Mpls traffic-eng tunnels mpls label range 300 399 Pop Label Pop Label IP 10.1.12.0/24 IP 1.1.1.1/32 For the LAN interface, a 1- byte circuit ID is appended to the 6- byte SysID of the specified intermediate system ( DIS ) to form a 7- word. After the configuration is complete, the level 2 LSP sent by R2 will carry the cipher text authentication TLV information (the level 1 LSP is not carried). If this configuration is maintained, we will find that R2 can only learn the R1 release. Routing, this is because level1 LSPs are not authenticated. After completing this experiment, R3 and R4 complete the configuration. And OSPF difference is that a router must belong to a whole region, the border area can not on the router, it said, the interface can not belong to a certain area, the other interface belonging to other regions (Tunnel0) Destination: 4.4.4.4 ! Can form adjacencies with other L2 (or L1/L2 ) routers *Aug 18 11:26:02.546: 10.1.12.2 Mainly used to replace type 2 TLVs to provide larger metrics. In addition, it also supports IS-IS based MPLS TE 75000 Interface Ethernet0/0 300 RSVP-TE requests to establish an LSP tunnel according to the above path. Summary of tag processing actions Device Internet segment 10.1.xy.0 / 24 , where xy is the device number, X small y large Redistribute isis ip level-2 into level-1 route-map test ! 959 The PATH message is sent to the end of the hop by one hop; the RESV message is sent to the headend router in the opposite direction. Interface Loopback0 Remote binding: tsr: 2.2.2.2:0, tag: 201 tib entry: 10.1.12.0/24,ccna r&s exam code, rev 10 In fact, this is a metric trick, but when we are thinking about it, remember to take the virtual path of the tunnel into consideration. In the cfg-ip-expl-path mode, you can also use the list keyword to view all the next-addresses that have been entered . Use index x next-address to specify the index number of each next- hop IP that has been entered . The configuration of R2 is as follows (all configurations are omitted from the configuration of interface IP ): !! This one can be done, you know Interface eth 0/1 4.4.4.4 Tunnel mpls traffic-eng path-option 10 dynamic Reservable Bandwidth[1]: Network 10.1.23.3 0.0.0.0 area 0 Network 1.1.1.1 0.0.0.0 area 0 Next, look at R3 : The routing table of R3 is as follows (omit direct route): Interface loopback0 This will cause the route of R2 to change. The outgoing interface of the route to 5.5.5.5 and 55.55.55.55 becomes e0/1 . So R2 goes to 400 Status Set-overload-bit on-startup <5-86400 sencondes> Ip explicit-path name R3R4 enable next-address 10.1.23.3 For TE of ISIS extension Router# mpls traffic-eng reoptimize The configuration of R4 is as follows: (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 .
