The establishment of 3G networks will have a huge impact on wireless communication and will also promote the development of wireless network services, especially the development of multimedia services.

The ICMP redirection field, used by the router to notify the host of the optimal gateway to the target, is another vro on the data link.
Purpose:
1. Verify redirection.
2. The impact of redirection on host data forwarding.
3. Disable the data forwarding process after redirection.

Experiment Design:
1. R2, R3, R4, and R5 run the RIPv2 protocol. R1 disables the routing function and points the default gateway to R2.
2. the R4 and

[PURPOSE]
BGP Confederation is used to solve the BGP Route black hole problem caused by horizontal segmentation of IBGP.

[Experiment description]
R1, R2, R4, and R5 run the BGP protocol, while R2, R3, and R4 run the OSPF protocol. The objective is to make 1.1.1.1
The IBGP neighbor relationship is established using the loopback interface.

Title: n matrix multiplication, to find the least number of multiply operations and how to combineSuppose that matrix A is r1*r2 and matrix B is R2*R3, so m=a*b=r1*r2*r3. When multiple matrices are multiplied, the number of operations is different when the matrix is combined in different ways.Example: M=M1 * M2 * M3 * M4[5*20] [20*50] [50*1] [1*100]((m1*m2) *m3) *m4=5000+250+500=5750and M1* (m2* (M3*M4)) =5000+100000+10000=115000If you follow (m1* (M2*M3) *m4) =1000+100+500=1600The above examp

The problems that arise:
A) R1 has a 7.7.7.0/24 route on it, but Ping 7.7.7.7 is not reached. (R7 same)
Now view the R1 routing table

B 1.1.1.0 [20/0] via 5.5.5.5, 00:02:54/To save space incomplete display
It can be seen that R7 learned the route of the R1, from the surface to see the experiment is perfect, for the purpose, but then the problem arises, make a test, on the R7 ping R1
