Tristan, this fits into the discussion Nathan and I were having -- I'm currently using the single port method, and he is not.
>From what I can tell, Bearer traffic will use the bearer gateway, and management traffic will use the management gateway. I do not believe that there is any doubling back, so to speak. There are some firewall rules that Nathan can describe in greater detail, much of which you can find in the list archives. I have been finding radically different iperf behavior when testing the EPC's management interface directly on L2 vs. L3. I do not yet know whether this dichotomy affects bearer traffic; if anyone can confirm that would be awesome, as Telrad design docs appear to support both setups. I am possibly leaning toward Nathan's topology of porting all ENB traffic back over VPLS, as I already have a full MPLS stack available.
