Hola, Tengo 2 Cat 3750 con Imagen para Capa 3.
Como puedo configurar un mismo VTP Domain e InterVlan Routing para ambos Switchs?, cada uno esta conectado a routers distintos en distintos sitios, pero estan conectados en la misma lan por fibra optica. Quisiera que el intervlan y el vtp domain se mantenga en linea aun si el enlace de fibra optica este este caido
gracias

Hi,
To enable the VTP domain across the two sites, you need to have bridging enabled betwen the two routers, rather than a layer 3 routed link. VTP requires vlan 1 to be extended between the two sites in order to operate.

Both sitch are conected with FiberOptic Ethernet, and VTP cross it. i want that the intervlan and vtp domain still working if the fiber optic cable goes down. How i can do it?

Hi tjavier,
try out HSRP...

The only resolution for your second problem i can imagine is to use a backup link between your two switches..
Hope this is of any help.

the wan link can be the bakcup link?

Well, to be honest, I dont know.
I can't remember a constellation i have seen where HSRP is backed up by a wan link. Even if so, do u want all your traffic to travel over the wan? From my point of view, its a "notverygood" ;-) solution.
Hope this was of any help.
