Configuración de RIPv2

Tanto RIPv1 como RIPv2 tienen las siguientes funciones y limitaciones:
- Uso de horizonte dividido para ayudar a impedir routing loops.
- Limite máximo de 15 saltos, siendo 16 considerado red inalcanzable.
- Updates disparados cuando hay una topología para lograr una convergencia más rápida.

Diferencias de RIPv2 con RIPv1:
- Utiliza VLSM y CIDR (es un protocolo de enrutamiento con clase)
- Uso de direcciones multicast al enviar actualizaciones.
- Opción de autenticación disponible.

En la topología que se ilustra contiene 3 Routers interconectados LIMA, TACNA y TRUJILLO con sus respectivos direcciones IP, ahora hacemos el uso de la configuración RIPv2

Tanto LIMA, TACNA y TRUJILLO se configuran inicialmente como: nombre, dirección de interfaz, contraseña de consola, etc. al final hacemos el uso de la configuración RIPv2

Nota: para la contraseña y enable secret para esta topología sera:

Enable password: cisco

Enable secret: class

Configuración TACNA:

Router>enable 

Router#configure terminal 

Router(config)#hostname TACNA

TACNA(config)#enable password cisco

TACNA(config)#enable secret class

TACNA(config)#interface fastEthernet 0/0

TACNA(config-if)#ip address 192.168.2.1 255.255.255.0

TACNA(config-if)#no shutdown 

TACNA(config-if)#exit

TACNA(config)#interface serial 0/0/1

TACNA(config-if)#ip address 212.212.212.14 255.255.255.252

TACNA(config-if)#no shutdown 

TACNA(config-if)#end

TACNA#copy running-config startup-config 

TACNA#exit

Configuración TRUJILLO:

Router>enable 

Router#configure terminal 

Router(config)#hostname TRUJILLO

TRUJILLO(config)#enable password cisco

TRUJILLO(config)#enable secret class

TRUJILLO(config)#interface fastEthernet 0/0

TRUJILLO(config-if)#ip address 192.168.1.1 255.255.255.0

TRUJILLO(config-if)#no shutdown 

TRUJILLO(config-if)#exit

TRUJILLO(config)#interface serial 0/0/0

TRUJILLO(config-if)#ip address 212.212.212.9 255.255.255.252

TRUJILLO(config-if)#clock rate 64000

TRUJILLO(config-if)#no shutdown 

TRUJILLO(config-if)#end

TRUJILLO#copy running-config startup-config

TRUJILLO#exit

Configuración LIMA:

Router>enable 

Router#configure terminal 

Router(config)#hostname LIMA

LIMA(config)#enable password cisco

LIMA(config)#enable secret class

LIMA(config)#interface fastEthernet 0/0

LIMA(config-if)#ip address 192.168.3.1 255.255.255.0

LIMA(config-if)#no shutdown 

LIMA(config-if)#exit

LIMA(config)#interface serial 0/0/1

LIMA(config-if)#ip address 212.212.212.10 255.255.255.252

LIMA(config-if)#no shutdown 

LIMA(config-if)#exit

LIMA(config)#interface serial 0/0/0

LIMA(config-if)#ip address 212.212.212.13 255.255.255.252

LIMA(config-if)#clock rate 64000

LIMA(config-if)#no shutdown 

LIMA(config-if)#end

LIMA#copy running-config startup-config 

LIMA#exit

Ahora vamos a configurar RIPv2 en cada routers:

Configuración RIPv2 TACNA:

TACNA#configure terminal 

TACNA(config)#router rip 

TACNA(config-router)#version 2

TACNA(config-router)#no auto-summary 

TACNA(config-router)#passive-interface fastEthernet 0/0 Interfaz pasiva, la LAN (no recibe actualizaciones RIP)

TACNA(config-router)#network 192.168.2.0

TACNA(config-router)#network 212.212.212.12

TACNA(config-router)#end

TACNA#copy running-config startup-config 

TACNA#exit

Configuracion RIPv2 Trujillo:

TRUJILLO#configure terminal 

TRUJILLO(config)#router rip 

TRUJILLO(config)#version 2

TRUJILLO(config-router)#no auto-summary 

TRUJILLO(config-router)#passive-interface fastEthernet 0/0 Interfaz pasiva, la LAN (no recibe actualizaciones RIP)

TRUJILLO(config-router)#network 192.168.1.0

TRUJILLO(config-router)#network 212.212.212.8

TRUJILLO(config-router)#end

TRUJILLO#copy running-config startup-config 

TRUJILLO#exit

Configuración RIPv2 LIMA:

LIMA#configure terminal 

LIMA(config)#router rip 

LIMA(config-router)#version 2

LIMA(config-router)#no auto-summary

LIMA(config-router)#passive-interface fastEthernet 0/0 Interfaz pasiva, la LAN (no recibe actualizaciones RIP)

LIMA(config-router)#network 212.212.212.8

LIMA(config-router)#network 212.212.212.12

LIMA(config-router)#network 192.168.3.0

LIMA(config-router)#end

LIMA#copy running-config startup-config 

LIMA#exit
