The command is as follows (in the routing process): Three triggers that may cause the TE tunnel to reoptimize . In preparation, the same label is assigned to one FEC . Traffic belonging to one FEC has the same forwarding mode, forwarding path, and forwarding treatment.

Primary tunnel 1 byte defines NSEL . Therefore the NSAP address is at least 10 bytes. In the CISCO IOS in, the NSAP configured dotted 16 hexadecimal form. The AFI value of 49 can only be used locally,ccna icnd, and is the reserved private address space defined by RFC1618 . Extended IP reachability TLV (type 135 ) 75000 Create a " pseudo-node LSP " in the broadcast subnet and advertise all the routes in the subnet (the LSP is similar to the LSA ) 10.1.12.2 Load balancing of tagged messages 1.0.0.0/24 is subnetted, 1 subnets This command will cause the penultimate hop router to still carry the label when sending data to the end. This label is an empty label. Distribution mode : Label Distribution ! Device Configuration However, there may be such a problem that the LDP connection between R1 and R2 is broken for some reason, but between R1 and R2 . 10.1.23.3 Ip address 10.1.123.3 255.255.255.0 Affinity: 0x00000000 ..........................................

You can take a closer look at it, for example, look at R1 itself to generate LSA10 : *Aug 18 09:06:07.919: min unit=0 bytes, max pkt size=2147483647 bytes Ip unnumbered loopback 0 tunnel destination 5.5.5.5 tunnel mode mpls traffic-eng 0x00000029 *Aug 18 09:06:02.699: Tun Sender: 1.1.1.1 LSP ID: 247 Fast tag rewrite with Fa0/0, 10.1.34.3, tags commit: {303} via 10.1.15.5, 0 dependencies, recursive We know that by default, IS-IS is level1 area much like a Stub (but allow people to re-advertise external routes coming in, so just say they look like), Area within the L1 router through a default route to reach outside the region, which have A suboptimal path may be generated because he is looking for the nearest L1\L2 router in the region .
