Complete MPLS TE configuration on R1 . Type 2 length 48: The configuration of R1 is as follows: Router-id 3.3.3.3 10.1.23.3 [MPLS: Label 301 Exp 0] 124 msec 96 msec 104 msec Interface Tunnel0 MPLS TE Router ID: 2.2.2.2 Path Protection RSVP Pop Label Since the IP packet destined for 6.6.6.6 is sent to R2 ,ccna exam model question paper, the IP packet is pushed into the VPN label 505 under the inner layer , which is no problem. Then we continue, the VPNv4 route on 6.6.6.6 on R2 is passed by 5.5.5.5, which is R5 . Mpls traffic-eng router-id Loopback0 mpls traffic-eng area 0 Ip address 10.1.12.1 255.255.255.0 Log-adjacency-changes RFC2966 standardized from Level2 to Level1 leaked routes IP lookup and tag lookup Therefore, the router will not BGP direct distribution label route, but for BGP routes by next hop routing label distribution after the recursion, this is very good. BGP routing entry is pretty much, by this way we MPLS , can greatly simplify the performance loss routers, BGP 's Transit AS routing black hole problem has been solved. Mpls traffic-eng router-id loopback0 mpls traffic-eng area 0 // Prerequisites for advertising a label mapping message to a neighbor locally NSEL is 00 ( 1B from the right ) The system ID is 0000.0c00.1111 The area ID is 39.0f01.0002 !! Label protocol uses LDP (default is LDP ) 131 *Aug 18 09:06:02.699: Hop Addr: 10.1.12.1 LIH: 0x20000403 1bit Define source Set-overload-bit Fa0/0 1.0.0.0 In this way, my network resources will be more rationally utilized. When R1 goes to 1.0/24 and 2.0/24 , traffic will be sent to different tunnels on R1 . At this moment R1 is the head end of my tunnel , and R5 is the end. The tunnel can set bandwidth requirements so that my tunnel can make more scientific and reasonable routing in the network, not just using OSPF metric for routing. The calculation of the tunnel path is done on the R1, which is the tunnel first-end router. In order to enable the head-end router to calculate the tunnel path more reasonably (not only using metric , but also participating in the path with elements such as available bandwidth and link attributes. Computation), we need to extend the link state routing protocol running in the network, in order to flood the information required for more path calculations, extended OSPF and IS-IS can accomplish this task.
