ccna routing and switching sample test

Interface loopback1 Average rate=250000 bytes/sec, burst depth=1000 bytes 200 Create a TE tunnel on R1 , the source is its own loopback0 , and the destination is 4.4.4.4 of R4 . RSVP Path Info: Redistribute isis ip level-2 into level-1 route-map test Router ospf 1 Status: Or Tunnel Id MPLS application LSP ID Label subobject: Flags 0x1, C-Type 1, Label 200 4.4.4.4/32, Flags: 0x20 (No Local Protection, Node-id) Label subobject: Flags 0x1, C-Type 1, Label 403 5.5.5.5/32, Flags: 0x20 (No Local Protection, Node-id) This state has three values: down , init , up Show ip cef detail Show tcp brief Outgoing interface (Tunnel0) Destination: 4.4.4.4 *Aug 18 11:31:44.598: ISO 9542 NSAP address re-addressing The configuration of R2 is as follows (the tunnel is not configured temporarily ): 0/0/0 The port in TCP/IP . Is-type command such as is-type level-1 R3 is the ABR , connected area0 and area1 Ok, now when R1 is going to ping 4.4.4.4 ,ccna routing and switching sample test, R1 has to check its own FIB , which is the CEF table. Note that this is an IP lookup: 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. Local binding: tag: imp-null Traffic Engineering RouterID TLV (Type 134 ) is mainly used for TE 10.1.23.3 Send out from the Fa1/0 port. So, R2 replaces the tag with 300 and then throws it to R3 . 10.1.34.4 [MPLS: Label 403 Exp 0] 0 msec 0 msec 4 msec Note: a L1 / L2 router if the other area router adjacency relationship, it will to this area of the L1 router advertisement himself outlet, the specific method is the raw cost region L1 LSP when packets ATT bit Set 1 i ia 10.1.24.0 [115/148] via 10.1.123.2, FastEthernet0/0 There are four metric types: Max_reservable_bw_sub: 0 ​​(kbps) Local Switched Router-id 5.5.5.5 Different TLV field values ​​can be included in the LSP to advertise various different routing information. Interface Tunnel0 Now a result, since the R1 has the MPLS LDP-IGP synchronization, R1 will 10.1.12.0/24 this link metric transferred to 65535 (in fact, this time the R1-R2 between OSPF adjacency should DOWN off, will save the configuration If R1 is restarted, the OSPF adjacency relationship between R1 and R2 will not be established. Therefore, R1 is preferred as R4 as the next hop to the 3.3.3.3 network, and LDP adjacency is maintained between R1 and R4 .
