Oper: up If the sysID length is inconsistent, the IIH is ignored . Router ospf 1 RFC1195 To add: In the above environment, the loopback interface cost=1 , and the cost of all other physical interfaces =10 . Then if we configure: PATH i L1 10.1.34.0 [115/20] via 10.1.123.3, FastEthernet0/0 C 10.1.123.0 is directly connected, FastEthernet0/0 i* L1 0.0.0.0/0 [115/10] via 10.1.123.3, FastEthernet0/0 *Aug 18 09:06:07.919: Tun Dest: 5.5.5.5 Tun ID: 0 Ext Tun ID: 1.1.1.1 906 Tu0 ATT/P/OL Still this figure, but the configuration of R2 becomes: Globally activate MPLS TE tunnel and set MPLS label space DIS send HELLO interval ordinary packet router of 1/3 (default 3.3s ) Link[0 ]:Nbr IGP Id: 10.1.12.2, nbr_node_id:8, gen:47 frag_id 0, Intf Address:10.1.12.1 Advertising Router: 1.1.1.1 LS Seq Number: 80000001 Type 7 length 12: *Aug 18 11:26:02.546: ----------- The PoP : receives downstream air sent by the tag assigned to a specific prefix, the value of this tag is 3 , then the LSR to the downstream LSR transmits the prefix data destined time, he will put up top label ( the POP ) for Forward, note that this time only need to check for this LSR 75000 Router ospf 1 <0x0-0xFFFFFFFF> Attribute flags LSPID The configuration of R1 is as follows: Router(config)#tunnel mpls traffic-eng path-selection metric ? igp use IGP metric Domain-password !! Activate IS-IS on the interface Interface fast 0/0 Is-type command such as is-type level-1 Mpls ip interface fa1/0 O AutoRoute defect Maximum bandwidth : 12500000 10 Attributes are explicitly assigned to the TE tunnel through administration action. Extended IP reachability reachability TLV (type 135 ) [115/30] via 10.1.24.2, Serial0/0 2.0.0.0/24 is subnetted, 1 subnets !

The tunnel priority ranges from 0 to 7. The smaller the priority, the higher the priority. !! activation Tunnel of forwarding-adjacency Network 1.1.1.1 0.0.0.0 area 0 Of course, the above method is not safe. Therefore, in special cases,ccna exam braindumps, we may want the L1\L2 router to conditionally set the ATT bit and set it more controllable. Then we can associate the route-map and match a specific one in the route-map . Routing, as long as this route is in my routing table, route-map is satisfied, I will set ATT . The distribution of the label is like this: Mpls traffic-eng tunnels ip rsvp bandwidth There may be two levels of link state databases: Test and see the forwarding path of the data. So if you want to load balance based on messages ? OSPF IP Address: Metric: 10 CSPF algorithm working mechanism Lsp-refresh-inverval to modify. The label can be ejected on the (the penultimate hop). C only needs to find the FIB table to forward the received IP packet. Switched 1.0.0.0/24 is subnetted, 1 subnets IS-IS link type On the point-to-point link, the neighbor uses PSNP to acknowledge the new LSP . When the source router receives the PSNP acknowledgement sent by the neighbor , it stops sending new LSPs to this neighbor . In the LAN , there is no clear PSNP confirmation. The lost LSP can be detected. If any of the LSP missing or expired, Router are to PSNP send a request form to request retransmission of the LSP .
