Each IP packet forwarded to a router is the same before and after being forwarded through the router. Mpls traffic-eng router-id loopback0 mpls traffic-eng area 0 By selection ( level2 routing) LSP Checksum Note that at this moment,new ccna exam questions, 2.2.2.0/24 will not be learned on R4 . This external route is completely suppressed on R2 . R5 is also similar: Transport addr is generally equal to LDP ID unless it is specified by hand ( mpls ldp discovery transport-address ) . Note that here (described above) there are actually three kinds of addresses: interface IP , Transport addr , LDP ID ISO10589 Comparison of terms between IS-IS and OSPF : Outgoing interface Ip address 10.1.34.3 255.255.255.0 The fields of the same background color described above are all corresponding. LDP IETF standard ( TCP/UDP port number 646 ) TDP CISCO private ( TCP/UDP port number 711 ) Path establishment and maintenance Activate the MPLS TE extension for each router's OSPF and manually set the RouterID for MPLS TE . ID: path option 10 [8] ATT/P/OL * Aug 18 04: 37: 06.239 : Outgoing PathTear: !! dismantle tunnel OSPF and ISIS also have mechanisms for periodic flooding Tib entry: 4.4.4.4/32, rev 14 0 kbits/sec The maximum reservable bandwidth is 75M , which is 75% of 100M . Not triggered by ISH , once the interface is activated, the router floods the IIH message on the interface. The local device will actively advertise the generated label mapping message to all LDP neighbors. Mpls traffic-eng tunnels ip rsvp bandwidth FastEthernet0/0 (ldp): xmit/recv Enabled: Interface config MPLS TE of AutoRoute characteristics of the TE tunnel as a direct link participating SPF calculation (except R2 themselves) OSP PDU R3.02-00 MPLS application Debug isis update on R2 In this environment, since the tail end of the tunnel is at R4 , the label that R4 assigns to this tunnel through RSVP is POP . End host. For example , the ISO CLNP workstation searched by the ES-IS protocol . Interface Tunnel0 Mpls traffic-eng router-id loopback0 mpls traffic-eng area 0 We may as IS-IS of level1 or level2 assign an interface authentication password. If level2 is not specified , the default level1 authentication. If the interface is enabled for plain text authentication, the password is inserted into all IS-IS packets: IIH , LSP , CSNP , and PSNP (based on a specific level ). When actually capturing packets on the CISCO device, it is found that only the password information of the plaintext is carried in the IIH (placed for authentication).
