Otherwise, the LSR advertises all label bindings. *Aug 18 09:06:07.919: SENDER_TSPEC type 2 length 36: Hello data unit: sent periodically to determine whether other ISs are running IS-IS , establish adjacencies, exchange LSPs , and synchronize LSDBs . TE Metric is equivalent to the concept of weight value, note that this is to be distinguished from IGP metric OSI terminology 0 kbits/sec Checksum: 0x6FEB Length: 132 If the MPLS payload is an IPv4 or IPv6 packet, CISCO IOS is used in a destination-based load balancing environment. Options: (No TOS-capability, DC) LS Type: Opaque Area Link The CSPF calculation is performed by the head end of the tunnel , and the result of the calculation is a string of IP ( path of the tunnel ) Each ES belongs to a specific area, when the ES finds the nearest IS by listening to the HELLO ( ISH ) grouping of the intermediate system . 0/0/0 Label Ip address 10.1.23.2 255.255.255.0 RSVP message type The configuration of R1 is as follows ( R2 does not open area password temporarily ): description ! MPLS relies on IP routing and CEF switching The routing table for R1 is as follows (direct route is ignored): Clear domain authentication *Aug 18 09:06:07.919: 1.1.1.1 (Strict IPv4 Prefix,cisco exam test questions, 8 bytes, /32) Local label info: global/16 Ip cef Network 10.1.34.3 0.0.0.0 area 0 IPv6 , then it must publish routing information with this NLPID value. the term O bits are defined in OSPF in the option field is used to indicate whether the router has the ability to send and receive opaque the LSA . 4 10.1.45.5 8 msec 8 msec * i*L1 0.0.0.0/0 [115/10] via 10.1.123.3, FastEthernet0/0 Hello interval: 5000 ms; Transport IP addr: 1.1.1.1 LDP Id: 2.2.2.2:0; no host route to transport addr Once LDP is activated, the LSR generates a label locally for the prefix in the routing table, and then bundles it with the prefix to send the label mapping message to all LDP neighbors. When I receive the remote binding from the LDP neighbor , I bundle the tags and the local bindings that are localized for the specific prefix into the LIB . Net 49.0001.4444.5555.6666.00 Mpls traffic-eng tunnels ip rsvp bandwidth 1.0.0.2 ! Network 10.1.23.2 0.0.0.0 area 0 Neighbor relationship establishment Another example of causing IGP and LDP to be out of sync is that when the LSR is restarted, the IGP can quickly establish an adjacency, and the LDP session may be set up slowly, that is, the necessary information is loaded in the LFIB . IGP forwarding has already begun before the correct label exchange . The message may then be forwarded incorrectly or dropped somewhere after entering the MPLS network.
