Comprehensive experiment

The experimental requirements ： 

  First step ：IP Address planning

Master network ：192.168.1.0/24

Required network segment ：r1 Two loopback interfaces （2 Net segment ）+ r2 Two loopback interfaces （2 Net segment ）+ Two point-to-point backbone links （2 Net segment ）= 6 Net segment

First, it is divided into three network segments , They correspond to each other r1 r2 Backbone links

take 192.168.1.0/26--- Backbone links    192.168.1.64/26---r1   192.168.1.128/26---r2

Then divide it , Assign to the corresponding link and loopback interface

When dividing the backbone link network segment , Direct it to 30 position , Improve IP Utilization ratio . 

 

 

The second step ：IP Configuration of

We directly use the effective availability in the first step subnet IP, Configure each port of the router and the loopback interface IP

The third step ：RIP Configuration of

With r1 For example

First choose RIP Process number （ The default is 1）

[r1]rip ?

  INTEGER<1-65535>  Process ID （ Usable range ）

[r1]rip 1      The process number can be defined at startup ; The default is process 1;  Only local

RIP Version selection

[r1-rip-1]version 2  Choose the version 2

Make an announcement

First declare yes ：1、 Activate -- The selected interface can send and receive rip Information about     2、 Shared routing -- The network segment of the selected interface can be shared with all local neighbors     notes ：（RIP At the announcement , Only main network segments can be declared ）

r1 To declare yes, just declare 192.168.1.0 Network segment

[r1-rip-1]network 192.168.1.0

Same reason r2 And r3 Conduct RIP To configure , Then check the routing table of each

[r2]display  ip routing-table protocol rip    Check the routing entries generated by a protocol

r3

 

Default route

Because it cannot be announced directly r3 The loopback of , Therefore, the default routing configuration is required

[r3-rip-1]default-route originate

RIP Default route in ：  After defining the default source information on the border router , The default route will be published to the intranet , After that, the internal router will automatically generate a default route to point to the direction of the border router . But the border router points to ISP The default route for , Still need handwriting .

Manual summary

Due to the experimental requirements, try to reduce the number of routing tables , So we need to summarize manually

RIPV2 Manual summary of      You need to update the source router , Configure on the interface where all updates are sent

[r1]int g0/0/0

[r1-GigabitEthernet0/0/1]rip summary-address 192.168.1.64 255.255.255.192

Check... When you're done r1 And r2 The routing table can find that the routes to the two loopback interfaces are reduced to 1 strip

So far, this experiment is over , Achieve all experimental purposes

Add ：

RIP Extended configuration for

RIPV2 Manual summary of ： On the update source router , Configuration summary on the interface where all updates are sent

[r1]int g0/0/0

RIPV2 Certification of

Sent and received by neighbors RIP Add the authentication password in the message , At the same time, after Huawei starts the authentication of the interface , all rip The information will be encrypted , Between two directly connected neighbors , The authentication password and mode must be exactly the same .

[r1]interface g0/0/1

[r1-GigabitEthernet0/0/1]rip authentication-mode md5 usual cipher 123456

Silent interface （ Passive interface ）

Only receive and do not send routing protocol information ; It can only be used to connect the interface of the user terminal , It cannot be used for the interface directly connecting the router neighbor , Otherwise, the neighbors will not be able to share routing information

Speed up convergence

RIP timer    30s to update     180s invalid     180s Inhibition     300s Refresh

Modify the timer appropriately , It can accelerate the convergence speed of the protocol ; When modifying , All operations in the whole network rip The equipment recommendations are consistent ; Maintain the original multiple relationship ; And not easy to modify too small .
