VPN Between Efficient Networks router and BCM

Just curious if anyone has configured a gateway-to-gateway VPN with SpeedStream (Efficient Networks) router and BCM? I presently have two SpeedStream routers running our tunnel using IKE with pre-shared keys. We're getting BCM to our new building and I wondered how the configuration would be connecting the BCM to our branch office using the remaining SpeedStream router.
 
Your routers will create the infrastructure and the BCM will just be an enhancement on the network.

Have you a BCM at the head office and the branch office?

 
thx for the response marshall. no, i don't have a bcm in my branch office. my router in vegas is an ADSL router SpeedStream 5671 (I think that's the right number) and in Houston, it's a IDSL version of the same router. I wonder of the WAN side of the xDSL routers will ooerate if connected directly to the BCM or is it necessary that it is connected to a DSLAM.

It'd be great if the xDSL router will operate behind the BCM.
 
thnx again marshall. actually, it will be the opposite. our xDSL is provisioned by Covad. Moving to a new building we bought we also upgraded our Merlin hardware. SBC will provision a PRI, channelized T1 (I think my boss worked it down to 18 voice channels and the rest is data). SBC is terminating the T1 line to an Adtran TA624 and the BCM will connect to the Adtran (this is all by SBC design). Our Vegas office (on the SpeedStream router) will remain with Covad. In Houston now we'll have SBC providing the integrated services. On this configuration, I'm not even sure we will be connecting our switch to the Adtran or to the BCM. SBC's setup just seems to have redundance but that's what my boss signed up on - I thought the T1 can terminate directly with the BCM, but I don't really know much about it.

The configuration would appear to be this way:

PRI T1 (from SBC) -> Adtran TA624 -> BCM -> POTS/Data switch

What I'm researching is how I will build my VPN to Vegas - the Adtran integrated access device doesn't have a built-in VPN feature so I'm either going to buy another appliance or buy the license to enable the BCM VPN feature, whichever is cheaper. With the existing xDSL Efficient Networks (SpeedStream) routers, I use IKE with a preshared key - a painless solution for a LAN2LAN VPN. So that's how I got to this mess of trying to find out how to configure the VPN on the BCM to automatically negotiate the VPN tunnel using IKE with preshare key. If only the WAN side of the IDSL router can be connected directly to the data port on the BCM then I'll only need to change the WAN IP address on the IDSL WAN port to a local IP address behind the BCM. I'm just not sure that the WAN port on the router needs to be wired directly to a DSLAM, or if it's just a plain Ethernet port.

any thought you might have is 10^1000 greatly appreciated :)
 
the full config would be this:

[Vegas Data]
SpeedStream router (ADSL by Covad) -> internet cloud

[Houston Data]
internet cloud -> TA Adtran IAD (T1 PRI by SBC) -> BCM
 
You will probably find a VPN router cheaper than the keycode for the bcm
