Use index x next-address to specify the index number of each next- hop IP that has been entered . The default LDP label space is platform-based per-platform or device-based. What do you mean? Let's look at the B router, which bundles the label 34 for the prefix X , and publishes the label binding information to all LDP neighbors, which is the same for everyone, and everyone has a label 34 . This is based on the platform. Then there is an interface-based tag space. i ia 10.1.24.0 [115/148] via 10.1.123.2, FastEthernet0/0 10.1.23.3 [MPLS: Label 300 Exp 0] 108 msec 116 msec 64 msec Is-type level-1 metric-style wide For point-to-point interfaces, SNPA is the unique identifier for the circuit.

The router compares the local interface MTU with the received IIH size to ensure that it can be processed before forming the adjacency. The largest possible packet of neighbors. IS-IS by Hello PDU padding size to the interface MTU large Next, look at R3 : The target network segment involved in MPLS is the same as traditional IP forwarding.

EBGP adjacency is also established on the physical interface. All routers in the area (except the border router) can only establish neighbor relationships with routers in the area.

There is an LDP neighbor. Its LDP router ID is 2.2.2.2 and label spaceID=0 . This indicates that the platform is based on the label space. Area verification is actually the verification of Level1 area . After the area authentication is added to an IS-IS router, it will check the IS-IS packets it receives . If there is no authentication information or error in the packet, it will be ignored. The IS-IS packet generated by the device itself carries the authentication information. If the receiver does not have the configuration area authentication, the device can still learn normally after receiving the packet carrying the authentication information. The authentication information of the area authentication is only included in the LSPs packet. Other packets are not included.
