Ll Router , maintains first a layer LSBD , by default, L2 of the LSP is not flooded over, and therefore L1 router 's LSDB 10.1.12.2 Metric: 10 Ip rsvp bandwidth I mentioned the four metric types of IS-IS . The bits that can be used in each metric are the lower 6 bits. That is to say, the maximum interface metric is 63. We propose several new TLVs to make up for this defect. 1.1.1.1 The boundary of the area is on the link Bw[3]: Net 49. 0001 .0000.0000.0001.00 Here's what you can verify: Meanwhile, in order to avoid loops, R2 in the area level1 when injected these routes will be marked downbit , As a result, R3 receive this LSP , for these routes, it will not flood the backbone inside. Network 10.1.12.1 0.0.0.0 area 0 0x0000000C Above we can see the reservable bandwidth of all tunnel priorities. Now let's modify the reservable bandwidth of the tunnel with priority 6 . *Aug 18 09:06:02.699: Setup Prio: 7, Holding Prio: 7 End system adjacency routing R4.00-00 5.5.5.5 [110/2] via 0.0.0.0, 00:00:01, Tunnel0 Label subobject: Flags 0x1, C-Type 1, Label 200 4.4.4.4/32, Flags: 0x20 (No Local Protection,cisco ccna sample questions, Node-id) Label subobject: Flags 0x1, C-Type 1, Label 403 5.5.5.5/32, Flags: 0x20 (No Local Protection, Node-id) The two important thresholds in the LSP remaining time field are: LSP maxage and LSP refresh interval 4.4.4.0/24 The LSP overload-bit generated by this router is set. This will cause the router to not be used by other routers as the next hop to any destination, except for its locally connected network segment. This is generally used when the router is a leaf node, that is, the end of the network, directly connected to the user. PSNP (partial serial number PDU ) Outgoing Reserved label The configuration of R1 is as follows: AutoRoute: disabled LockDown: disabled Loadshare: 20000 bw-based auto-bw: disabled OutLabel : Ethernet0/0, 204 RSVP Signalling Info: ! Although the L1 / L2 router having both L1 and L2 function, but sometimes simply Establishing a specific interface on a layer adjacent relationship, are arranged on the other interfaces in the first 2 layers adjacent relationship. 10.1.23.0 [115/20] via 10.1.34.3, Serial0/0 75000 102 According to different IS-IS PDU types and specific network environments, the TLV ( Type/Length/Value ) field is immediately followed by various types of IS-IS PDUs . The PDU header and TLV fields form a complete IS-IS. PDU . In ISO10589 and RFC1195 these two current IS-IS standard, using the code ( code ) word, rather than the type ( type ), but since the TLV to other protocol standards, it TLV than CLV using multiple network literature Here we also use TVL instead of CLV . In IS-IS PDU variety used TLV , both ISO 10589 defined, there RFC 1195 defined.The TLVs defined in ISO are used in the CLNP network environment, but most of them are also used in IP network environments. The TLV defined in the RFC is only used in the IP environment. For an IS-IS PDU , you can carry a TLV that supports the CLNP protocol , and you can carry it.
