But why? The reason is that the label assigned by R2 to route 10.1.12.0 is PoP , because 12.0 is the directly connected network segment of R2 , and there is a second-end hop pop-up mechanism. Then this IP packet is R2 to stop the meal , because R2 does not have 6.6.6.6 and 5.5.5.5 routing. How to do? The re-addressing process is similar to zone merging and separation, except that during re-addressing, some or all of the router's zone prefixes need to be cleared, with new ones. Section LAN ID as 1921.6811.1001. 03 . " the routers connected to the multiaccess network (Ethernet) all have the same circuit ID .

Activate IS-IS on the interface After the MPLS LDP-IGP synchronization is activated on an interface , the IGP will advertise the metric of the link to the maximum until the synchronization is complete or the LDP session is successfully established on the interface. In OSPF , the metric is up to 65535 . In this way, it can be guaranteed that no path will pass through the interface when LDP is in the disconnected state.
