Affinity Bit : 0x0 IGP Metric : 1 Next-address 10.1.45.5 Type : 0x8848 (Multicast) The upper layer carries MPLS , looking for LFIB The default LDP label space is platform-based per-platform or device-based. What do you mean? Let's look at the B router, which bundles the label 34 for the prefix X , and publishes the label binding information to all LDP neighbors, which is the same for everyone, and everyone has a label 34 . This is based on the platform. Then there is an interface-based tag space. The loopback0 address space of all devices is xxxx/32 , and x is the device number. *Aug 18 09:06:07.919: Path Latency (microseconds):0 2.2.2.2/32 Time since created: 11 minutes, 42 seconds Time since path change: 10 seconds Number of LSP IDs (Tun_Instances) used: 9 Ip address 2.2.2.2 255.255.255.255 R1#show ip route Downstream on Demand max hop count: 255 Downstream on Demand Path Vector Limit: 255 LDP for targeted sessions 10.1.12.2 (Link ID) Network/subnet number: 2.2.2.2 (Link Data) Network Mask: 255.255.255.255 Number of MTID metrics: 0 All routers run OSPF and the entire network is interconnected. The IP plan is as shown in the figure. Loopback0 of all devices is addressed by xxxx/32 , and x is the device number. Reservable Bandwidth[1]: Remote binding: tsr: 2.2.2.2:0, tag: 202 tib entry: 10.1.23.0/24, rev 12 End host. For example , the ISO CLNP workstation searched by the ES-IS protocol . ! 10.1.12.2 Complete sequence number packets ( CSNP ) Complete sequence number packet In order to ensure the simplicity of the experimental environment first, I will ignore the existence of the R4 and R4 direct links. When you don't exist, you will be there. Ip address 55.55.55.55 255.255.255.255 Res. Sub BW: 0 kbits/sec Downstream:: Mpls traffic-eng tunnels ip rsvp bandwidth Link connected to: another Router (point-to-point) (Link ID) Neighboring Router ID: 5.5.5.5 R3(config)#Interface tunnel 0 TTL Signalling: connected To form an adjacency relationship. Mpls ldp router-id Loopback0 For certification Provide a loop-free network During the ES-IS work process, the end system sends an ESH ( ES Hello ) message to a specific address to notify the router of its existence. The router listens to the ESH packet to discover the ES existing in the network , so that the packet arriving at the specific ES address is subsequently forwarded to the ES . In ES-IS , the router advertises its own existence to the ES by sending an ISH ( IS Hello ) message to a specific address . ES also monitor ISH ,cisco ccna practice test pdf, if a plurality of received IS transmitted ISH , ES will then be selected, and sends all data to the IS .
