otherwe'll see.This diagram is interesting, in R2, the general practice is to create an OSPF process with a process number, while declaring your own two straight connections into this OSPF process, but in order to explain the local meaning of the OSPF process ID, I use two OSPF on the R2 ProcessID created two OSPF processes and declared the R2 straight connector, in other words, R2 uses OSPF process 20 to establish a neighbor relationship with R1, using OSPF process 30 to establish an OSPF neig

Yesterday my colleague asked me a question, there are two circular statements: Copy Code code as follows: for (i = n; i > 0; i--) { ... } for (i = 0; i { ... } Why is the former faster than the latter? My explanation at the time was: I-the operation itself affects CPSR (the current program State Register), CPSR Common flags have n (result is negative), Z (result is 0), C (with Carry), O (with overflow). I > 0 can be judged directly by the Z-sign. The i++ o

COST value 1. Topology: 2. Configuration and Description: 1. Configure the IP address and ospf protocol of each interface. I used an R0 router to configure a frame relay switch. This helps us better understand frame relay. Note: When R1 and R4 use the FR interface, you can define the interface type ip ospf network broadcast or manually specify the neighbors of the two interfaces. Otherwise, the neighbors may fail. 2. Then we can manually specify the cost value through the interfaces of each rout
