Configure Router

Display interface information

show ip interface brief


Obviously, we haven't to set the router port

Before we configure router interface, we have to enter the privilege mode

enable

Enter terminal

configure terminal

Set interfaces separately

# interface ethernet 0/0
# ip addr 192.168.69.1 255.255.255.128
# no shutdown


OK now, we finished one.
and then, we have to configure another subnet.

exit  

# interface ethernet 0/1
# ip addr 192.168.69.129 255.255.255.128
# no shutdown

Now, we configure already

testing

阿晟 ping appleWatch : success
阿晟 ping 筆電 : success





乾 不能保存 WTF !!! (the question has been solved. try use (write momory) )

Remark

if we pad ? to part of the command, it will display remaining words

## 3 Equal route


### Topology

### Import startup configure file


### Specify the loopback ip
r1

r1(config)#interface loopback 1
r1(config-if)#ip address 1.2.3.4 255.255.255.0


r3

r3(config)#interface loopback 1
r3(config-if)#ip address 1.2.3.4 255.255.255.0


Vpc

VPCS> ip 192.1.1.2 255.255.255.0 192.1.1.1

### Using EIGRP configure routers

r1

r1(config)#router eigrp 100
r1(config-router)#no auto-summary
r1(config-router)#network 0.0.0.0
r1(config-router)#network 12.0.0.0

r2

r2(config)#router eigrp 100
r2(config-router)#no auto-summary
r2(config-router)#network 0.0.0.0
r2(config-router)#network 12.0.0.0
r2(config-router)#network 23.1.0.0
r2(config-router)#network 192.1.1.0

r3

r3(config)#router eigrp 100
r3(config-router)#no auto-summary
r3(config-router)#network 0.0.0.0
r3(config-router)#network 23.1.0.0

R2 route table

## Equal routing setting

### CEF == False
Default is True.

r1(config)#no ip cef
r2(config)#no ip cef
r3(config)#no ip cef

Ping 1.2.3.4

R1 0/0

R3 0/0

## 4.Summary

172.16.12.1
172.16.13.1
172.16.14.1
172.16.15.1

經過偶的計算
用22去用因為

15 = 000011 11
14 = 000011 10
13 = 000011 01
12 = 000011 00

sub mask = 255.255.252.0

Manual summary

we could use the previous strapup file so that we can't need to set a similar configuration again.

r1(config)#interface loopback 1
r1(config-if)#ip address 172.16.12.1 255.255.255.0
exit
r1(config)#interface loopback 2
r1(config-if)#ip address 172.16.13.1 255.255.255.0
exit
r1(config)#interface loopback 3
r1(config-if)#ip address 172.16.14.1 255.255.255.0
exit
r1(config)#interface loopback 4
r1(config-if)#ip address 172.16.15.1 255.255.255.0
exit

R2

r2(config)#router eigrp 100
r2(config-router)#network 0.0.0.0


Setting

R1(config-if-range)#interface range e0/0
R1(config-if-range)#ip summary-address eigrp 10 172.16.12.0 255.255.252.0
