TROUBLESHOOTING FRAME RELAY
Router 1
Errores:
1. Se encuentra mal configurado el mapeo Frame-relay map ip 172.18.221.2 678 broadcast
para R1.
2. Falta agregar Frame-relay propio
3. La interfaz Serial0/2/1(DTE) de R1 se encuentra con clock-rate configurado.
Soluciones:
1. Se realiza la corrección del error mediante el comando:
#Frame-relay map ip 172.18.221.2 182 broadcast
2. Se debe agregar el mapeo Frame-relay:
#Frame-relay map ip 172.18.221.2 182
3. Se debe eliminar el clock-rate de la interfaz DTE usando el comando:
#no clock-rate 125000

Router 2
Errores:
1. Se configuro clock-rate en una interfaz DTE
2. Se realizó mal la configuración en el Frame-relay map
3. Se configuro el LMI como ANSI, mientras el resto de routers están como cisco
4. No se configuro una contraseña en línea virtual
Soluciones:
1. Se debe eliminar el clock-rate de la interfaz DTE usando el comando:
#no clock-rate 125000
1. Se debe cambiar la configuración del mapeo Frame-relay:
#frame-relay map ip 172.18.221.1 181 broadcast
2. Se debe cambiar la configuración del LMI a cisco:
#frame-relay lmi-type cisco
3. Se debe establecer una contraseña en línea virtual:
#line vty 0 4
#password cisco
#login

Errores:
1. Falta agregar la ruta Frame-relay desde R2 con DLCI 182 a R1 con DLCI 181
Soluciones:
