5.1.3 Configuring Transmission Data
This section describes how to configure transmission data for EG860 in typical service scenarios.
Context
EG860 provides the following three transmission modes for configuration. Select a transmission
mode based on the networking.
l
Routing Behind MS
When Routing Behind MS is applied, the uplink data will be forwarded via the available
routes of EG860. The downlink data will be forwarded to EG860 according to the route set
on the core network side.
l
NAT
NAT is to translate the
address in the packet header of the
data to another
l
GRE
GRE encapsulates data packets of some network-layer protocols such as
and IPX. The
encapsulated data packets can be transmitted over another network-layer protocol such as
. GRE adopts the tunnel technology and belongs to the Layer 3 tunnel protocol of
tunnel is a virtual point-to-point connection that provides a path for transmitting the
encapsulated data packets. Data packets are encapsulated and decapsulated at the two ends
of a tunnel.
l
transmits PPP packets over a tunnel, allows a Layer 2 termination point and a PPP
session endpoint to reside on different devices, and exchanges information using the packet
switching technology, to extend the PPP model.
combines the advantages of the L2F
and PPTP protocols, and is an industry standard set by IETF.
Configuration principles for the four transmission modes are as follows:
l
Four transmission modes both support one or more attached devices under an EG860.
However, the operation for the Routing Behind MS transmission mode is relatively simple.
l
If the network cannot traverse the public network, Routing Behind MS is recommended.
If the network traverses the public network, NAT and GRE are recommended.
l
When multi-cast services are required, only use GRE transmission mode.
l
When Layer 2 networking transmission is used, only
tunnel transmission can be
used.
l
tunnel transmission is used, loopback networking must not be used. That is,
two EG860s must not connect to the same switch.
