Ccnp2 Tunnel

CONFIGURACION DE UN TUNEL GRE SEGURO

Topología:

1.- Configurar interfaces físicas y lógicas.

R1# configure terminal
R1(config)# interface loopback0
R1(config-if)# ip address 172.16.1.1255.255.255.0
R1(config-if)# interface fastethernet0/0
R1(config-if)# ip address 192.168.12.1 255.255.255.0
R1(config-if)# no shutdown

R2# configure terminal
R2(config)# interfacefastethernet0/0
R2(config-if)# ip address 192.168.12.2 255.255.255.0
R2(config-if)# no shutdown
R2(config-if)# interface serial0/0/1
R2(config-if)# ip address 192.168.23.2 255.255.255.0R2(config-if)# clockrate 64000
R2(config-if)# no shutdown

R3# configure terminal
R3(config)# interface loopback0
R3(config-if)# ip address 172.16.3.1 255.255.255.0
R3(config-if)# interface serial0/0/1R3(config-if)# ip address 192.168.23.3 255.255.255.0
R3(config-if)# no shutdown

2.- Configurar Protocolo EIGRP 1

R1(config)# router eigrp 1
R1(config-router)# no auto-summaryR1(config-router)# network 192.168.12.0

R2(config)# router eigrp 1
R2(config-router)# no auto-summary
R2(config-router)# network 192.168.12.0
R2(config-router)# network 192.168.23.0

R3(config)#router eigrp 1
R3(config-router)# no auto-summary
R3(config-router)# network 192.168.23.0

3.- Configurar el tunel GRE

R1(config)# interface tunnel 0
R1(config-if)# ip address 172.16.13.1255.255.255.0
R1(config-if)# tunnel source fastethernet0/0
R1(config-if)# tunnel destination 192.168.23.3

R3(config)# interface tunnel0
R3(config-if)# ip address 172.16.13.3 255.255.255.0R3(config-if)# tunnel source serial0/0/1
R3(config-if)# tunnel destination 192.168.12.1

4.- Configurar protocol EIGRP 2 sobre el tunel

R1(config)# router eigrp 2
R1(config-router)# noauto-summary
R1(config-router)# network 172.16.0.0

R3(config)# router eigrp 2
R3(config-router)# no auto-summary
R3(config-router)# network 172.16.0.0

5.- Crear políticas IKE y peers....
