Fa0/0 The L1 and L2 IIH PDUs on the LAN are sent to different multicast MAC addresses: L1 is 0180-C200-0014 , L2 is Router ospf 1 !! means from 13.1 to 34.3 and then to the local ( 34.4 ) 1.0.0.0 75000 Device Internet segment 10.1.xy.0 / 24 , where xy is the device number, X small y large Ip cef 0 kbits/sec 10.1.34.4 10.1.45.4 10.1.45.5 5.5.5.5 Interface Ethernet0/1 !! Note area0 and area1 must activate MPLS TE Switched *Aug 18 11:26:02.546: Activate RSVP on the interface and configure reserved bandwidth (optional) ! Mpls ldp router-id loopback0 RESVErr is sent to the tail router The status here is active . When the primary link does not expire,testking cisco exams, status is displayed as ready Type The usual practice is to use mpls ip to activate the LDP protocol on each interface that runs the IGP protocol. There is an easier way: Show mpls ldp discovery detail Show mpls ldp parameters Show mpls ldp neighbor SystemID Length : Identifies the length of the system ID . A value of 0 indicates a length of 6B , a value of 255 indicates a length of 0 , and other system ID fields may have a length of 1-8 bytes. First of all, all routers run routing protocols, and the entire network is interoperable. Next, LDP is activated on the interface of the router, and an LDP adjacency relationship is formed between the two routers . Bandwidth change Then show it: Network 10.1.34.4 0.0.0.0 area 0 (Link Data) Router Interface address: 0.0.0.13 Number of MTID metrics: 0 Net 49. 0002 .0000.0000.0001.00 Ip address 10.1.34.4 255.255.255.0 Router(config)# mpls ldp advertise-labels [for prefix-access-list [to peer-access-list ] ] Interface is up and sending maximum metric Interface eth0/1 105 Clear domain authentication R1 is isis neighbor directly is empty, because it ignores received on this interface R2 of hello packets. Local binding: tag: imp-null Config Parameters: BGP routing problem, well, now we use the loopback interface on R1 and R4 to establish IBGP adjacency, the problem is solved. At this time R4 , the go 5.5.5.5 next hop of the R1 of Loopback port addresses, R4 at destined to 5.5.5.5 of the IP when the pressure package label, use is 1.1.1.1/32 routing tag, The same is true for R3 and R2 , then the label package can be opened through 1.1.1.1/32 . Use of OSI IS-IS for Routing in TCP/IP and Dual Environments Mpls ldp igp sync holddown msecs <0x0-0xFFFFFFFF> Attribute flags Router(config-if)# mpls traffic-eng path-option x {dynamic | explicit name y } [ lockdown ] ! Each priority corresponds to an available bandwidth Fa0/0 Link connected to: a Transit Network 10.1.34.4 Link state ID For the first layer LSP database, you use the first 1 layer CSNP and PSNPs , for the first 2 used in the first layer 2 layer CSNP FastEthernet1 / 0, Src IP addr: 10.1.13.3 Addresses bound to peer LDP Ident: Multicast packets belonging to a specific multicast group ! The TLV field of the LSP . Here, in addition to the system ID that contains the neighboring IS , there is a bunch of metrics. ----------- *Aug 18 04:37:06.239: version=0, length in words=7 This NSAP address is still a bit longer, and it is inconvenient to use. The SystemID is mainly used to identify several attributes, such as adjacency information, LSP identifier in IS-IS database, etc. In most cases, We are more suitable for symbols that have literal meanings, such as R1 and R2 , rather than a string of numbers. So CISCO IOS provides us with a very good way: the mapping of the router hostname to the NSAP address. Essentially the mapping of hostname to SystemID . There are two methods of static mapping and dynamic mapping.
