Pequeña guía básica para enrutar caminos en un router Cisco.
Rutas estáticas
- Configurar una ruta estática (ip route)
r2>enable
Password:
r2#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
r2(config)#ip route 192.168.1.0 255.255.255.0 192.168.2.1
r2(config)#end
%SYS-5-CONFIG_I: Configured from console by console
r2#
- Ver rutas conectadas (show ip route)
R2#show ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS le
ia - IS-IS inter area, * - candidate default, U - per-user stati
o - ODR, P - periodic downloaded static route
Gateway of last resort is 0.0.0.0 to network 0.0.0.0
172.1.0.0/16 is variably subnetted, 3 subnets, 2 masks
S 172.1.0.1/32 [1/0] via 172.4.0.2
D 172.1.0.0/16 [90/297246976] via 10.10.12.25, 10:06:16, Tunnel2
S 172.1.0.3/32 [1/0] via 172.4.0.2
D 172.2.0.0/16 [90/310046976] via 10.10.12.25, 10:06:10, Tunnel2
D 172.3.0.0/16 [90/310046976] via 10.10.12.25, 10:06:14, Tunnel2
C 172.4.0.0/16 is directly connected, FastEthernet0
D 172.5.0.0/16 [90/310046976] via 10.10.12.25, 06:22:36, Tunnel2
D 172.7.0.0/16 [90/310046976] via 10.10.12.25, 00:14:59, Tunnel2
D 172.8.0.0/16 [90/310046976] via 10.10.12.25, 10:06:12, Tunnel2

Rutas Dinámicas
- Activar el protocolo de enrutamiento (route)
Router(config)# router name_of_the_IP_routing_protocol
Router(config-router)#
- Para consultar tipos de protocolo (route ?)
r2(config)#route ?
eigrp Enhanced Interior Gateway Routing Protocol (EIGRP)
ospf Open Shortest Path First (OSPF)
rip Routing Information Protocol (RIP)
r2>enable
Password:
r2#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
r2(config)#route rip
r2(config-router)#network 192.168.0.1
RIP Configuration
-Opción 1:
R2(config)# router rip
R2(config-router)# network IP_network_#
R2(config-router)# version 1|2
-Opción 2:
r2(config)# interface type [slot_#/]port_#
r2(config-router)# ip rip send version 1 | version 2
- Ejemplo
r2>enable
Password:
r2#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
r2(config)#route rip
r2(config-router)#network 192.168.0.1
r2(config-router)#network 172.0.0.1
r2(config-router)#version 2
r2(config-router)#
