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
- 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"

Prueba de comunicación
1. Pruebas de vecindad entre los router:
Router1#show cdp n
Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge
S - Switch, H - Host, I - IGMP, r - Repeater, P - Phone
Device ID Local Intrfce Holdtme Capability Platform Port ID
Switch Gig 0/0 133 S 2960 Gig 1/1
Router2 Ser 0/0/0 141 R C2900 Ser 0/0/0
Router2#show cdp n
Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge
S - Switch, H - Host, I - IGMP, r - Repeater, P - Phone
Device ID Local Intrfce Holdtme Capability Platform Port ID
Switch Gig 0/0 136 S 2960 Gig 1/1
Router1 Ser 0/0/0 149 R C2900 Ser 0/0/0
2. Tabla de ruta
