Next Hop Clear text area certification (Link ID) Designated Router address: 10.1.12.1 (Link Data) Router Interface address: 10.1.12.2 Number of MTID metrics: 0 Time since created: 11 minutes, 42 seconds Time since path change: 10 seconds Number of LSP IDs (Tun_Instances) used: 9 1/0/0 Ip cef IS-IS packet format !! Use strict next hop directly in this area 75000 Fa0/0 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: *Aug 18 04:37:06.239: Tun Sender: 1.1.1.1 LSP ID: 20 The interface will be created. We just need to put the traffic into the tunnel port, there are still a lot of methods, we will continue to introduce in the following content. Overview 0 kbits/sec Mpls ip Traditional IP routing only considers metric when routing . For example, if we are running OSPF in the above figure , then R1 to 1.0/24 and 2.0/24 will preferably be from R2 to R3 . Path because the metric is small. Then this directly causes the idle of another optional path and the excessive congestion of the main path. Clear text interface authentication Local LDP Identifier: Outgoing tag or VC Route summary example 2 on the L2 router Fa0/0 If there is a loop (usually a problem with the IGP , such as a misconfiguration of the static route), the TTL in the tag header will prevent the tag packet from being forwarded indefinitely. !! OSPF cost of the interface OSI PDU Establishment of LIB and LFIB tables 200 By default, an OSPF area is not a stub and can be configured as a stub. Used to uniquely identify an LSP and authentication source router O Shutdown off R2 in e0 / 1 port in R1 crawl debug information Tib entry: 4.4.4.4/32, rev 14 Use the clns host command in global configuration mode to establish a mapping of hostnames to NSAP addresses. In this way, in the link state database, LSP LSP Checksum Fast tag rewrite with Fa0/0, 10.1.12.2, tags commit: {203} via 10.1.12.2, FastEthernet0/0, 0 dependencies Prefix R1#show isis neighbors Router ospf 100 Priority range 0-7 , the smaller the priority 300 R2 is preferably a route from the tunnel port. At this time , the traffic from R2 to 55.55.55.55 is on the tunnel , and the LSP is used for label switching. Tag Interface eth 0/0 The Level 2 LSP contains all the prefix information that may be reached in IS-IS . Level1 LSP is only used in the local area. Fast Reroute ( FRR ) is a link or node protection mechanism. Allows the headend router to rerouting when there is a problem with the link or node , and uses a temporary, pre-established path to bypass the point of failure. See Opaque information here, there are a number of TLV (Type Length Value), which TLV so OSPF may carry data by means of a stretchable manner. These TLVs carry specific MPLS TE data. There are two kinds of TLVs : router address TLV and link TLV. Network 10.1.23.2 0.0.0.0 area 0 MPLS TE improves the efficiency of traffic spread across the network, avoiding inadequate and overuse of links. 75000 Since RSVP has been able to complete the task of label allocation, there is no need to activate the Label Distribution Protocol ( LDP ) on the interface . In the routing table, R3 goes to 1.1.1.1 and uses 10.1.34.4 and 10.1.23.2 equivalent load balancing. RFC 2763 10.1.34.0/24 The first 6 is the setup priority and the second 6 is the hold priority . Peer LDP Ident: 3.3.3.3:0; Local LDP Ident 2.2.2.2:0 TCP connection: 3.3.3.3.62244 - 2.2.2.2.646 The introduced IP route changes. As a result, the size of the LSPDB is greatly reduced. Note that the above picture is just an abstraction and simulation concept. The ABCD four routers actually have ISIS adjacencies (in IS-IS broadcast). In the network, adjacencies are formed between routers of the same level on the same network segment, including all non- DIS routers. This is different from OSPF . However , after DIS , everyone The resulting LSP volume is reduced. That is to say,cisco mock exam, although all routers on the IS-IS broadcast network form an adjacency relationship, the synchronization of the LSDB is still guaranteed by the DIS . The LSP stability and reliability has been guaranteed. The operation of the SPF algorithm is naturally faster.
