Remote binding: tsr: 2.2.2.2:0, tag: imp-null Mainly contains TE tunnel bandwidth request Network Service Access Point . It is a conceptual point on the boundary between the network layer and the transport layer. It is the location where the OSI network layer serves the transport layer. Each transport layer entity is assigned a unique NASP address. The maximum reservable bandwidth is 75M ,ccna certification exam questions and answers 2016, which is 75% of 100M . Frame-relay map ip 10.1.123.1 201 broadcast Mpls traffic-eng router-id loopback0 mpls traffic-eng area 0 For example, to perform interface ciphertext verification between R1 and R2 : We found, R2 external routing re-released locally gone; R2 from level2 injection level1 of inter-area routes are gone; while R2 can not be used as R1 next hop of the default route. There is only one R2 local direct connection 24.0 route.

This one can be done, you know Network 10.1.45.4 0.0.0.0 area 1 IS R2.00 Pop tag Admin: up Use the lockdown keyword (note that the above configuration is configured in the TE tunnel port). Interface eth 0/1 Debug isis update on R2 The TTL diffusion process of the IP- label packet is described above . Now let's look at the TTL diffusion process from label to label . IS-IS interface. If the interface is attached to a multiaccess network, the circuit ID is concatenated with the system ID of the DIS ” Mpls ldp router-id loopback0 Tunnel destination 5.5.5.5 The database is also calculated by the CSPF algorithm, and the result is the path of the tunnel — a sequence of IP addresses. 103 R1(config)#interface fa0/0 IS-IS Level-1 Link State Database: Bytes tag switched 10.1.34.4 4.4.4.4 !! LSP path The downstream label was not transmitted, because LDP Neighbor was not established. Network 10.1.34.3 0.0.0.0 area 0 MPLS VPN configuration Use the exclude-address command to control the LSP from passing through a node (interface or router). You can use this keyword to match an interface IP or an MPLS TE router ID to let the tunnel path bypass a certain link or a router. Interface FastEthernet0/0 R1 goes from R2 and then goes to tunnel . The cost of this path is cost=10+1+1=12 The configuration of R3 is as follows: Tib entry: 1.1.1.1/32, rev 2 FastEthernet0/0 Process ID 1, Area 0 twenty two Fa0/0 Show mpls ldp bindings 880 Or Tunnel Id 75000 4 is IPv4 . If it is 6 or IPv6 , the LSR uses this value to determine whether the message is V4 or V6 , and then selects a complex equalization algorithm according to different IP versions. MP ( Merge Point ): Convergence point, which is the end of the backup tunnel. It can also be understood as the junction point of the primary tunnel and the backup tunnel. Obviously due to the lost and R3 direct link, R1-R3 between the LDP adjacency hung up, in terms of natural LIB table, before R3 pass over the bundled label will be lost, and now, if R1-R3 Between the link replies, they have to re-establish LDP adjacency and resend the label bundle. Time since path change: 10 minutes, 34 seconds Number of LSP IDs (Tun_Instances) used: 521 Reservable Bandwidth[7]: Three-way handshake mechanism: Ip unnumbered Loopback0 tunnel destination 4.4.4.4 tunnel mode mpls traffic-eng Ip vrf VPN-A rd 2345:6 IS-IS With BDR , the DR cannot be preempted, and the DR sends Hello at the normal frequency.

The SystemID is mainly used to identify several attributes, such as adjacency information, LSP identifier in IS-IS database, etc. In most cases, We are more suitable for symbols that have literal meanings, such as R1 and R2 , rather than a string of numbers. So CISCO IOS provides us with a very good way: the mapping of the router hostname to the NSAP address. Essentially the mapping of hostname to SystemID . There are two methods of static mapping and dynamic mapping.
