It has been verified by experiments. 1 Tunnel mpls traffic-eng autoroute announce Device Internet segment 10.1.xy.0 / 24 , where xy is the device number, X small y large 1230 Do not need to explain it again? At R4 , R4 pops the top label and forwards the packet to R5.

This external route is completely suppressed on R2 . Interface based : Per-Interface Value Version=0 length in words=10 Experimental phenomena The figure above is a single-area Level2 routing domain. 366 Basically, the LSP is the path through the MPLS network or a part of it that packets take. // One-way path. In fact, an LSP is a path when a packet traverses an MPLS network or a part of an MPLS network. Tunnel mpls traffic-eng autoroute announce !

Activate CEF Interface eth0/1 i L1 Ip explicit-path name R2R3R4 enable next-address 10.1.12.2 A new LSP is triggered immediately and the ATT is not set. As a result, R1 revokes the default route that originally pointed to R2 . OSPF is LSADB 0 kbits/sec Therefore, R2 receives the packet destined for 6.6.6.6 and first pushes the inner VPN label of 505 . Router(config-if)# mpls traffic-eng attribute-flags ? 0/0/0 The L1 router only forms an adjacency with the L1 router (or L1/L2 router ) in this area. Route Distinguisher: 2345:6 IS-IS only supports reliable diffusion on point-to-point links, and the spread on the broadcast link is unreliable. However, periodic broadcasts through DIS The configuration of R2 is as follows: Terminal system ES Delay metric is optional, the link transmission delay is not supported.

Each bit can represent an attribute of the link (such as whether it is encrypted or not) or a managed policy. There is no specific syntax for this 32bits . Each bit can be set to the latter without moving it. The network designer can think of specifying a specific meaning for a particular bit as needed . LSPID LSP Seq Num LSP Checksum LSP Holdtime ATT/P/OL Interface Ethernet0/0 Router-id 4.4.4.4 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, 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.
