Multiples Gateways.

Hola,

 

Multiples Gateways.

 

Quería preguntaros si es posible el uso de 2 default gateways a la vez para distintos SSIDs. El uso de la métrica en al intefaz VLAN sirve para asignar una ruta u otra?

 

Con rutas estáticas 

 

Use the following command to configure multiple default gateways with different nexthop IP addresses when DHCP import is not configured:

 

(host) (config) #ip-profile

(host) (ip-profile) #route 0.0.0.0 0.0.0.0 192.168.1.1 10

(host) (ip-profile) #route 0.0.0.0 0.0.0.0 192.168.9.1 20

 

The following example configures multiple default gateways under the VLAN interface when the default gateway is obtained from DHCP:

 

 

ip-profile

default-gateway import dhcp

 

interface vlan "10"

metric 10

ip address dhcp-client

!

interface vlan "20"

metric 20

ip address dhcp-client

!

 

Multiple Default Gateway Support
Mobility Access Switch allows you to configure multiple default gateways using the metrics option. Lower metric takes precedence when both routes co-exist. The second gateway with higher mertrics takes over when the first route is down.
The multiple default gateways can be configured in two different ways:
- When DHCP import is not configured for the default gateway, you can configure multiple routes with metrics under the IP profile to support multiple default gateways.
- When DHCP import is configured for the default gateway, you can configure the metrics value under the VLAN interface used for the uplinks to support multiple default gateways. This can be configured only from the CLI.

 

gracias y saludos!

Re: Multiples Gateways.

Las métricas para lo que sirven es para dar prioridad a una ruta frente a otra. Si una ruta tiene una métrica más baja, el controlador mandará el tráfico por allí.

Re: Multiples Gateways.

Gracias Samu,

 

y en el caso de éstas rutas:

 

(host) (ip-profile) #route 0.0.0.0 0.0.0.0 192.168.1.1 10

(host) (ip-profile) #route 0.0.0.0 0.0.0.0 192.168.9.1 20

 

Solo usa la segunda ruta si el next hop de la ruta con métrica menor está down?
