ISR 4451-X bridge

[bnw000001]

I'm trying to setup a VPN using ISR 4451-X routers, and I just need to bridge the input interface to the VPN tunnel.  I have found plenty of examples that show creating a bridge-group and assigning the bridge-group in the specific interfaces.  Unfortunately, I don't see the bridge-group command under the interfaces on the ISR 4451-X router.  I see a global bridge command for creating the bridge, but I don't know how to connect an interface to a bridge.

Can someone please point me to documentation that describes how to create bridges on the ISR 4451-X?

Thank you

You can't bridge a layer 2 interface, like an Ethernet interface, to a layer 3 interface, like a Tunnel.  If you want to link two sites by layer 2 you'll need to use something like L2TP (which can run over IPSec).

Could you describe the end goal you are trying to achieve?
