HCIA (network elementary comprehensive experimental exercise)

The experimental requirements

 

IP Division of address ：

First of all, we need to know how many network segments are needed in the figure , Then divide and configure

The following figure shows my divided subnet

According to the above figure, all interfaces of the router 、 Loopback interface IP To configure

After the configuration is completed, we first configure the single arm route under the topology

VLAN Configuration of  

Operating instructions

[sw1]vlan b    
[sw1]vlan batch 2 3    ( establish VLAN2 and 3)

Divide the interfaces on the switch into corresponding interfaces vlan in

[sw1]interface Ethernet0/0/1     （ Divide an interface into corresponding vlan）

[sw1-Ethernet0/0/1]port link-type access   （ First, modify the interface to the access mode ）

[sw1-Ethernet0/0/1]port default vlan 2   （ Then divide the interface into corresponding vlan in ）

trunk main rd ： It doesn't belong to any one vlan, Carry all vlan Traffic forwarding , Can mark （ encapsulation ） distinguish （ decapsulation ） Different vlan The label of .

[sw1]interface e0/0/3

[sw1-Ethernet0/0/5]port link-type trunk （ Modify the interface trunk Pattern ）

[sw1-Ethernet0/0/5]port trunk allow-pass vlan 2 to 3  

After the above configuration , You can view the of two switches VALN Forms

<lw1>display vlan

  

 

notes ： Configure the switch connected to the router trunk when , The interface connected with the router should also be configured trunk

Static routing  

Due to the requirements of the topic, dynamic routing should not be used , So we need to supplement the routing table through static routing

[r1]ip route-static 192.168.3.0 24 192.168.2.2

                           （ Target segment ）    （ Next jump ）

Follow this command , In turn R1---R5 Perform static routing configuration （ Except direct connection ）, In the face of R2 The loopback configuration of should be summarized , Due to the routing black hole generated after the summary, empty interface configuration is required

[r1]ip route-static 1.1.0.0 22 NULL 0

                        （ After summarizing the network segment ）

Finally, configure the default route , Both point outward to the boundary route

[r1]ip route-static 0.0.0.0 0.0.0.0 192.168.1.1

                                                    （ Next jump ）

NAT Address translation

At this time, the experimental requirements have been basically completed , Just in R5 on NAT Address translation deployment

[r5]acl 2000

[r5-acl-basic-2000]rule permit source any

[r5]int g0/0/1

[r5-GigabitEthernet0/0/1]nat outbound 2000

---

  So far, all the requirements of the experiment have been met , End of experiment .
