Конфигуриране на PPP при Cisco маршрутизатори

Примерна топология

В примерите се използва статично маршрутизиране на трафика между двете LAN мрежи.

Конфигуриране на PPP без автентификация

Маршрутизатор R1

enable
configure terminal
hostname R1
interface gi0/0
ip address 10.0.0.1 255.0.0.0
no shutdown

interface s0/0/0
encapsulation ppp
ip address 11.0.0.1 255.0.0.0
clock rate 4000000
no shutdown

exit
ip route 172.16.0.0 255.255.0.0 11.0.0.2
end

Маршрутизатор R2

enable
configure terminal
hostname R2
interface gi0/0
ip address 172.16.0.1 255.255.0.0
no shutdown

interface s0/0/0
encapsulation ppp
ip address 11.0.0.2 255.0.0.0
no shutdown
exit

ip route 10.0.0.0 255.0.0.0 11.0.0.1
end

Конфигуриране на PPP с автентификация PAP

Обърнете внимане на конфигурираните потребители на R1 и R2!

Маршрутизатор R1

enable
configure terminal
hostname R1
interface gi0/0
ip address 10.0.0.1 255.0.0.0
no shutdown

interface s0/0/0
encapsulation ppp
ppp authentication pap
ppp pap sent-username R1 password cisco
ip address 11.0.0.1 255.0.0.0
clock rate 4000000
no shutdown
exit

user R2 secret cisco

ip route 172.16.0.0 255.255.0.0 11.0.0.2

end

Маршрутизатор R2

enable
configure terminal
hostname R2
interface gi0/0
ip address 172.16.0.1 255.255.0.0
no shutdown

interface s0/0/0
encapsulation ppp
ppp authentication pap
ppp pap sent-username R2 password cisco
ip address 11.0.0.2 255.0.0.0
no shutdown
exit

user R1 secret cisco

ip route 10.0.0.0 255.0.0.0 11.0.0.1

end

Конфигуриране на PPP с автентификация CHAP

Маршрутизатор R1

enable
configure terminal
hostname R1
interface gi0/0
ip address 10.0.0.1 255.0.0.0
no shutdown

interface s0/0/0
encapsulation ppp
ppp authentication chap
ip address 11.0.0.1 255.0.0.0
clock rate 4000000
no shutdown
exit

user R2 secret cisco

ip route 172.16.0.0 255.255.0.0 11.0.0.2

end

Маршрутизатор R2

enable
configure terminal
hostname R2
interface gi0/0
ip address 172.16.0.1 255.255.0.0
no shutdown
interface s0/0/0
encapsulation ppp
ppp authentication chap

ip address 11.0.0.2 255.0.0.0
no shutdown
exit

user R1 secret cisco

ip route 10.0.0.0 255.0.0.0 11.0.0.1
