OSPF DE ÁREA ÚNICA
1.- Verificar conectividad con PING desde el Router hacia PC y Router vecinos
2.Habilite OSPF de área 0
R2(config)#router ospf 10R2(config-router)#network 200.210.221.0 0.0.0.255 area 0
R2(config-router)#network 200.210.222.128 0.0.0.3 area 0
R2(config-router)#network 200.210.222.132 0.0.0.3 area 0
R2(config-router)#end
3. Verificar el anuncio de redes con "show ip route"
Router#show ip routeCodes: L - local, 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 level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
a - application route
+ - replicated route, % - next hop override
Gateway of last resort is not set
