Solution: Establish a targeted LDP neighbor relationship between R2 and R4 The overload feature is, after all, a product of an era in which device performance is not strong enough. However , the extended application of overload is very worthy of attention. Let's take a look at the following picture: 10.1.34. 4 4.4.4.4 Ok, now when R1 is going to ping 4.4.4.4 , R1 has to check its own FIB , which is the CEF table. Note that this is an IP lookup: Set-overload-bit on-startup wait-for-bgp Generated 4 In the default implementation mode, the IIH packet is filled to the outbound interface MTU size (using the method of adding padding , as shown above). 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. 10.1.12.2 4 msec 4 msec 0 msec Then shut down the e0/1 port of R2 : Indicates the available status of a router resource. If the bit is set,cheap ccna training, it indicates that the router is overloaded. Overloading means that the performance of the router is suppressed due to insufficient CPU and memory resources. It was set overload field that LSP does not diffuse in the network and is calculated by the overload routing the router will not use the LSP .
