Routers in the network must identify all in order to perform appropriate operations OSPF is LSADB The tunnel configuration of R2 is modified as follows: The figure above is a single-area Level2 routing domain. *Aug 18 09:06:07.919: In the ES and IS neighbor relationship is established between Router bgp 123 *Aug 18 11:26:02.546: Route-target export 2345:5 MPLS is a CISCO proprietary protocol, later IETF borrowed, in IETF is called Tag Switching , can be understood as both a different name when enabled, the protocol used is not the same Fa0/0 PSN can reduce the number of flooding spreads and database synchronization. LIB tag information base Network 2.2.2.2 0.0.0.0 area 0 Version/ Protocol ID extension: Value is 1 MPLS TE information distribution By default, summaries go into Level 2 if no routing level option is indicated. The routing table for R1 is as follows: In general,ccna uk, any router that checks for a corrupted LSP will be corrupted by sending a remaining lifetime to 0 . IS-IS Level-1 LSP R1.00-00 IS reachability [2]: We see that in the LFIB of R3 , going to the destination of 1.1.1.1 , there are two label paths for load balancing. Ip cef *Aug 18 04:37:06.239: Metric Type: TE (default) Route-target export 2345:5 R2-PE1#show ip route According to the protection object can be divided into: *Aug 18 09:06:07.919: parameter id=127, flags=0, parameter length=5 The area address groups configured on the router are listed. It only appears in non-pseudo nodes Router-id 4.4.4.4 55.55.55.55 [110/2] via 0.0.0.0, 00:00:01, Tunnel0 MPLS TE Bandwidth: 20000 kbps (Global) Priority: 7 7 Affinity: 0x0/0xFFFF The tag data sent to it by R7 indicates whether the data belongs to R6 or R7 through different inbound tag values . The endpoint LSR in the LSP needs to know the bandwidth of the link and other parameters. Therefore , the routing protocol of the MPLS TE endpoint (first and last LSR ) must be a link state routing protocol. Through the link state protocol, routers in each area have a comprehensive understanding of the topology of the area. In this way, the first-end LSR knows how to schedule the use of MPLS traffic engineering-based LSPs .
