Is anyone else seeing a lot of 'strange' IPSEC traffic? We started seeing logs

You should be able to setup a VPLS between 3 (or more) devices. Something like

Example: VFI on a PE Device
The following example shows a virtual forwarding instance (VFI) configuration:

All i can say is good luck. We see the 'trash-bag mod' on a lot of AT&T aerial

I don't like the way they do their licensing (your license runs out, the box is
