Interface question

[DManigo]

I have a C827 router. The DSL configuration uses BVI1 (Bridge Virtual Interface 1) interface. I am configuring a network for VoIP services. I created the data VLAN on the switch and was wondering if the same VLAN will have to be configured on the core router? Being the configured interface is BVI1, do I have to create a sub-interface for the VLAN? Is it possible to create a bridge virtual sub-interface?

TIA

What switch are you referring to? Is this a switch that connects to the ethernet interface? Can you explain a little bit further?

To connect a router into a switch and be able to access VLANS on that switch you would need to create a VLAN trunk port, which I don't think that you can do on the 800 series routers.

the switch is an C1900 series.The 1751v4 will only be configured with the CME IOS and handle Voice protocols only.
My goal is to have everything (VoIP and internet access) route through the C827.

Hope this helps

Do you've got a 1900 series switch with two VLAN's and that connects into an 827 DSL router. So where does the 1751 fit in?

As I said, to connect a router to a switch and have multiple VLAN's access that router it would have to be on a trunk port which the 827 can't do.
