75000 Next, we do the following configuration in the tunnel of R1 : Network 10.1.34.3 0.0.0.0 area 0 If it is a frame relay primary interface or a P2MP sub-interface, it is required to be a fully interconnected PVC . For details, see the relevant sections of this document. ! Reservable Bandwidth[6]: It was dismantled and then continued to be removed. ! Domain-password cisco 75000 RSVP Signalling Info: Broadcast multi-access link This global command is used to modify it. After the expiration of the timer, the IGP will establish an adjacency on the link. Once the IGP adjacency is established and the LDP session has not been synchronized, the IGP will advertise the metric of the link to the maximum. Generated [1]: 75000 kbits/sec 4.4.4.4/32 R2 will immediately trigger a new LSP and clear the ATT , which causes R1 not to use R2 as the next hop for the default route. SysID Record Route: 2.2.2.2(200) 4.4.4.4(403) C Network 10.1.34.3 0.0.0.0 area 0 Important difference: RFC 3786 Interface loopback The PATH message is sent to the end of the hop by one hop; the RESV message is sent to the headend router in the opposite direction. LSA Note that we are studying the label allocation of frame-mode . Of course, if you are running in a single zone, you can use a full L1 router or a full L2 router solution. 5 14 A label switch router (LSR) The re-addressing process is similar to zone merging and separation, except that during re-addressing, some or all of the router's zone prefixes need to be cleared, with new ones. In preparation, the same label is assigned to one FEC . Traffic belonging to one FEC has the same forwarding mode, forwarding path, and forwarding treatment. 1.1.1.1/32 Tunnel priority As a result, the Level 1 LSP sent by R1 carries the cipher text authentication TLV . However, since R2 does not enable authentication, the LSPs sent by R1 are sent to R2 . R2 ignores the authentication information in the LSP and directly reads the LSP . Therefore, R2 can learn the route advertised by R1 . Of course, there is no R1 routing. My Address: 10.1.12.1 Prefix First of all, these three commands all work on the route obtained by the route calculated by the TE tunnel with the autoroute feature enabled . The above command changes the cost of the tunnel interface itself . Prefix Two routers to establish LDP neighbors, to ensure that the parties to the other side of the LDP ID triple up It can be seen that ES-IS plays a role in the CLNS network environment as if the ICMP , ARP and DHCP protocols in the IP network work together. Explicit Route: 10.1.12.2 10.1.23.2 10.1.23.3 10.1.34.3 5 The first 6 is the setup priority and the second 6 is the hold priority . Reservable Bandwidth[2]: Pop Label There are four metric types: 300 Type 1 length 8 : The label mapping message that is advertised locally is meaningful to the global . The labels corresponding to the same FEC advertised from different interfaces are the same. Then we go to R1 and test it: Local tag Record Route: NONE Interface loopback1 The external route is not carried in the LSP . Network 5.5.5.5 0.0.0.0 area 0 Bytes tag switched *Aug 18 11:31:44.598: Label Space ID is generally 0 , indicating that our label is a platform - based ( Per-platform ) label space. Local tag *Aug 18 09:06:07.919: 10.1.12.1 (Strict IPv4 Prefix, 8 bytes, /32) Precautions: L1 / L2router with the set attached-bit route-map associated with a route-map test deny the route-Map , it. The above figure encapsulates a three-layer label package. For an LSR , only the first label is processed. Each layer of the label has a bottom of the BoS stack to indicate whether it is already the bottom of the stack of the label, and the last label has BoS=1 . The loopback0 address space of all devices is xxxx/32 , and x is the device number. Neighbors should use PSNP to confirm this LSP 1.1.1.1 [110/3] via 10.1.34.4,ccna practice exam download, 00:53:36, FastEthernet1/0 Interface fast1/0 R2 (config-keychain)#exit *Aug 18 11:31:44.598: Continue to show it: NSEL is 00 ( 1B from the right ) The system ID is 0000.0c00.1111 The area ID is 39.0f01.0002 ! 10.1.12.2 ! Fragment number : 0 *Aug 18 04:37:06.243: average rate = 250000 bytes/sec, burst depth = 1000 bytes The loopback0 address space of all devices is xxxx/32 , and x is the device number. Discovery Sources: Router ospf 1 During the establishment of the adjacency relationship, the neighbors send CSNPs to each other (the CSNP is not sent after the adjacency is established ). MPLS TE provides the following solutions: Interface eth 0/2 Bandwidth parameter is the bytes as a unit Ip address 10.1.24.4 255.255.255.0 Area-password The configuration of R4 is as follows: Interface Ethernet0/1 Of course, the above method is not safe. Therefore, in special cases, 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 configuration of R3 is as follows: Or Tunnel Id R1#show mpls traffic-eng tunnels 2 *Aug 18 09:06:07.919: parameter id=127, flags=0, parameter length=5 Time since created: 11 minutes, 42 seconds Time since path change: 10 seconds Number of LSP IDs (Tun_Instances) used: 9 *Aug 18 11:31:44.598: Holdtime LSP packet structure Min unit=0 bytes, max pkt size=2147483647 bytes Focus on the 2.2.2.2/32 entry.

ES-IS can be said to be a "language" or routing protocol between an end system and a router. It is used to enable the end system and router on the same network segment or link to discover each other and allow the ES to learn its network layer address.
