Configuración Cisco PPP y CHAP

Configuración Cisco PPP y CHAP


Escenario


Se realizara la configuración de pc y equipos cisco, en una topología punto a punto, se empleará encapsulación PPP y autenticación CHAP



Configuración Cisco PPP y CHAP



  • PC1 --> 192.168.1.100 / 255.255.255.0, gateway 192.168.1.1
  • Router1 --> G0/0 192.168.1.1 / 255.255.255.0, S0/0/0 200.200.200.1 / 255.255.255.252 



  • PC2 --> 192.168.2.100 / 255.255.255.0, gateway 192.168.2.1
  • Router2 --> G0/0 192.168.2.1 / 255.255.255.0, S0/0/0 200.200.200.2 / 255.255.255.252



  • Router1 y Router2, encapsulación PPP
  • Password protocolo autenticación  CHAP "cisco"



Desarrollo

1. Uso de Cisco Packet Tracer para realizar las pruebas.
2. Configuración de PC1 y PC2 con sus respectivas direcciones IP y gateway.
3. Configuración de Router1 como sigue:
hostname Router1
!
username Router2 password 0 cisco

!
interface GigabitEthernet0/0
