Chapter 4
Remote Node Configuration
This chapter is about parameters that are protocol independent.
The protocol-dependent
configuration will be covered in subsequent chapters.
4.1 Remote
Node
Overview
A remote node is required for placing calls to a remote gateway. A remote node represents both the remote
gateway and the network behind it across a WAN connection. Note that when you use
Menu 4
to set up
Internet access, you are actually configuring one of the remote nodes.
4.2 Remote
Node
Setup
This section describes the protocol-independent parameters for a remote node.
4.2.1 Encapsulation and Multiplexing Scenarios
For Internet access, you should use the encapsulation and multiplexing methods used by your ISP. For a
LAN-to-LAN application, e.g., branch office and corporate headquarters, prior mutual agreement on
methods used is necessary because there is no mechanism to automatically determine
encapsulation/multiplexing. Selection of which encapsulation and multiplexing methods to use depends on
how many VCs you have and how many different network protocols you need.
Scene 1. One VC, Multiple Protocols
PPPoA
(RFC 2364) encapsulation with
VC-based
multiplexing is the best combination because the extra
protocol identifying headers that
LLC-based
multiplexing uses are unneeded. The PPP protocol already
contains this information.
