*Aug 18 04:37:06.243: version = 0 length in words = 7 Periodically send CSNPs every 10S in the broadcast subnet to flood LSPs Bw[2]: Router-id 1.1.1.1 Explicit Route: 10.1.12.2 10.1.23.2 10.1.23.3 10.1.34.3 The term link is a path between two ISs (routers). When two adjacent SNPAs can communicate, the link is in the UP state. The final R1 on the show isis database The tag object in the RESV message is advertised to the upstream router (the penultimate hop). This tag is the inbound tag in the tail router LFIB table. Router(config)#tunnel mpls traffic-eng path-selection metric igp R1#sh mpls forwarding-table The configuration of R3 is as follows: So far, the basic configuration has been completed. Now let 's create a TE Tunnel on R2 : Flowspec 10.1.23.0/24 R3(config)#Interface tunnel 0 0x0000000E L1/L2 router re-releases external routes into IS-IS ( to level2 ) 5.5.5.5/32, version 22, epoch 0, cached adjacency 10.1.34.3 10.1.23.3 Total Allocated BW (kbps) Fa0/0 10.1.45.4 10.1.45.5 Fa0/0 Holding timer : Hold time, default 30S Mpls traffic-eng router-id loopback0 mpls traffic-eng area 0 All routers in the area (except the border router) can only establish neighbor relationships with routers in the area. Router# show mpls traffic-eng link-management bandwidth-allocation Redistribute isis ip level-2 into level-1 route-map test Area-password cisco Ip address 4.4.4.4 255.255.255.255 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. Type 2 length 48: ISO10589 Router-id 3.3.3.3 Interface loopback0 Going is the tunnel . therefore: At 0XFFFFFFFF , this router will suspend the IS-IS process for MaxAge + ZeroAgeLifetime seconds, so that the LSP corresponding to this router in the entire routing domain is deleted. The IS-IS process is then restarted and the LSP is sent starting with sequence number 1 . (In fact, this situation will not arise,ccna mock, because even generate a per LSP , but also to 136 years after the serial number can be from 1 to reach 0XFFFFFFFF .
