Mpls traffic-eng tunnels mpls label range 300 399 *Aug 18 09:06:02.699: parameter id=127, flags=0, parameter length=5 The composition of the router , Backbone must be continuous. 668 S 4.4.4.4 is directly connected, Tunnel0 75000 The configuration of R2 is as follows: Router# show mpls traffic-eng link-management bandwidth-allocation *Aug 18 04:37:06.239: average rate=250000 bytes/sec, burst depth=1000 bytes R1 goes from R2 and then goes to tunnel . The cost of this path is cost=10+1+1=12 ! The link ID can be the router ID of the neighbor . If it is a multiple access link, it is the interface address of the DR . Experiment 2 Route summary divides the original segment of LSP into two segments If the two LDP neighbors do not match each other when they exchange parameters, this command can slow down the trial LDP session establishment time between the two LDP LSRs . If the session establishment fails, the next retry interval. Will multiply until the maximum-backoff timer expires.

Cisco routers support up to three NET addresses by default , which can be modified using the following command: Pop tag Interface fast1/0 Tunnel priority Mpls traffic-eng tunnels ip rsvp bandwidth For Level1 router , the area number is required to be the same. Active Path Option Parameters: The configuration of R2 is as follows: Supports allocating network resources for explicit LSP tunnels 0 kbits/sec Mpls traffic-eng tunnels ip rsvp bandwidth !! Only one interface activates MPLS TE R5 and R6 each announce their own Loopback route in the BGP process. Fa0/0 Tunnel: FR The DLCI 1 Which table is specifically checked depends mainly on the Layer 2 encapsulation of the received data. For example, if the Layer 2 encapsulation is Ethernet (data frame), look at the value of the Type / Length field of the frame header : 0x10BA Bytes tag switched Attribute Flags: 0x00000000 10.1.23.0/24 Downstream assigned label OSP PDU The above label, there is another way to see, is to look at the TE Tunnel directly on R2 : 1.1.1.1 104 Mpls traffic-eng tunnels ip rsvp bandwidth Mlps ldp neigbor [vrf vpn-name] ip-addr password [0-7] pswd It periodically changes tunnel bandwidth(BW) reservation based on traffic out tunnel. Ip address 10.1.255.1 255.255.255.255 R2#sh mpls tr link-management advertisements label. Link IP Address: 10.1.12.2 R1#sh mpls forwarding-table For example, in the above example, tunnel0 is established in R3 to R7 . For R1 and R2 , they do not know the existence of the tunnel . When they go to 7.7.7.7/32 , only the IGP 's own routing is performed. Calculation, then R2 is likely to take the path of R4-R6-R7 , but we may prefer that these traffic can be transmitted through the tunnel , then for this requirement, autoroute can not be achieved, need to use Forwarding ajacency .
