VLANs across a PPP link

[bregimand]

Here's my setup:

Office A has a 3500 switch and a 1721 router that is point to point-ed to a 1721 in Office B. Router B is connected to another 3500 series. Then, there is another 1721 connected to the same switch which then goes onto the internet.

I have 2 VLANs created on switch B - one for data and one for voice. I need the VLANs to propogate to network A so that I can get a VoIP system configured.

What, if anything, needs to be done on routers A and B in order for this to work?

SOrry if this has been asked - I searched and coulb't find it.

Thanks,

Paul

You want briding control protocol (BCP), it essentially allows PPP links to carry Dot1q tagged packets. Check it out here:

Thanks for the link! I looked everywhere for that before posting... It's exactly what I needed.
