Specifying the VPN label processing mode
The VPN label processing mode of an egress PE can be either POPGO or POP:
• POPGO forwarding—Pop the label, and then search for the outbound interface according to the
label and forward the packet out of the interface.
• POP forwarding—Pop the label, and then search the FIB to find the outbound interface and forward
the packet out of the interface.
