    Hi,

     

    Given we are running MPLS with LDP through the network core, will we require MPLS at all on the Network facing interface of the SRX to be "popped" or will this occur on the router connected to the SRX and then the IGP takes over?

     

    Thank you

    HI Clive,

     

    Default is implicit null that PE/Edge router will signal to pop the label (transport label) and PE gets VPN label.

    Optionally one can configure explicit-null in that PE will do pop for label(s) till bottom of stack.
