Three tables FastEthernet0/0.12 (ldp): xmit/recv !! Note that running MPLS , IP cef must be turned on Router isis 100 . An MP-iBGP connection is established between R2 and R5 . The interface of each router activates RSVP and MPLS TE tunnel support. 0 kbits/sec [Note] Label behavior of Frame Mode 75000 Interface tunnel0 Ip ospf cost 1 In the dynamic setup, let the tunnel head end router calculate the path that the TE tunnel can traverse the network to the tail end in an optimal manner. We only need to configure the destination of the tunnel , and then the first-end router uses the CSPF algorithm to calculate the path itself. 880 Mpls traffic-eng tunnels ip rsvp bandwidth Bw[5]: !! Don't forget the mapping of CLNS 1 Ip rsvp bandwidth 2000 This command sets the total reservable bandwidth of the interface to 2M. 3 Both R3 and R5 must activate the forwarding adjacency feature. See below for more details. As with regular IP routes , OSPF floods LSAs when the interface is up or manually modified for IGP interface parameters. We saw R4 assigned to the LDP label 403 with the prefix 5.5.5.5/32 in the LFIB table of R2 . Mpls traffic-eng router-id loopback 0 mpls traffic-eng level-1 Ip address 2.2.2.2 255.255.255.255 RSVP path establishment process Ip cef The port in TCP/IP . Ip unnumbered Loopback0 MPLS TE considers the attribute parameters of the link (such as delay, jitter, etc.) ! O Mpls traffic-eng area 0 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 ) Router bgp 2345 My Address: 10.1.23.2 The configuration of R2 is as follows (all configurations are omitted from the configuration of interface IP ): Kbps (Global) Priority: 6 6 Affinity: 0x0/0xFFFF MPLS TE can change the bandwidth and attribute parameters of the link through adaptation. Ip address 10.1.56.6 255.255.255.0 10.1.23.2 TLV Run the interface configuration command: isis metric value level-1 | level-2 to configure the metric on the same interface. Mpls traffic-eng tunnels mpls label range 200 299 16 1bit At this time, R2 goes to 55.55.55.55 , and the traditional IP data is taken instead of the LSP . The status here is active . When the primary link does not expire, status is displayed as ready The above is the debug information under normal circumstances . 103 R3.02-00 *Aug 18 11:31:44.598: 55000 MPLS TE overview In-label Out intf/label Tunnel mpls traffic-eng bandwidth 2000 There are three types of PDUs : the IS-the IS of ES-IS and CLNP Type the IS : first 1 ,ccna exam topics and syllabus pdf, 2 bits for indicating the type of router is L1router or L2router Fa0/0 Adding the force keyword will take effect immediately. Otherwise, only when the interface selected as the routeriD is DOWN , the reselection will be performed. Note: The router ID of the LDP neighbor must have reachable routes locally. 10.1.12.2 [MPLS: Label 200 Exp 0] 4 msec 0 msec 0 msec Router ospf 1 .......................................... ISO10589 The existence of the established tunnel has changed. The network environment at this moment is as follows: LDP initial/maximum backoff: 15/120 sec LDP loop detection: off !

LABEL Router ospf 1 Net 49.0001.1111.2222.3333.00 Traditional TTL operation This relative command can be configured with a value of -10 to 10 . This means adding or subtracting this specific value based on the IGP metric. For example figure above, without considering the tunnel in the case of, R2 on about 5.5.5.5 and 55.55.55.55 Routing Metric = 31 is . This value has been said above. Now we configure this with relative -1 after the command keywords, relying on autoroute calculated, point tunnel0 mouth of OSPF routing, Metric becomes 31-1 = 30 .
