Software Release 2.7.1
C613-02047-00 REV A
There are many configurable parameters for PPP interfaces that you can
modify using the SET PPP command.
By default, Allied Telesyn routers and layer 3 switches use Link Quality
Reporting (LQR=ON) to determine link quality on PPP links. When connecting
to some vendors’ routers it may be more suitable to turn LQR (link quality
reporting) off on PPP links (LQR=OFF), and instead use LCP Echo Request and
Echo Reply messages to determine link quality (ECHO=ON):
SET PPP=ppp-interface ECHO=ON LQR=OFF
For more information about PPP, see the Point to Point Protocol (PPP) chapter in
the Software Reference.
Dynamic PPP Interfaces and PPP Templates
A request from a lower layer (ISDN, ACC or L2TP) to create a new PPP
interface creates a Dynamic PPP interface. PPP templates are blueprints that
enable the full range of configuration options available on static PPP interfaces
to apply to dynamic PPP interfaces.
You can use a template to specify any of the parameters configurable on a static
PPP interface. Once a template is created, this template can be associated with
an ISDN, ACC or L2TP call.
PPPoE
PPP over Ethernet (PPPoE) is defined in RFC 2516 “A Method of Transmitting
PPP Over Ethernet”. PPPoE is used to run PPP over the Ethernet. The same
authentication, billing and transfer systems as for PPP are then available in
Ethernet networks.
PPP over Ethernet enables multiple hosts at a remote site to share the same
access device, while providing the access control and billing functionality of
dial-up PPP connections.
The router behaves as a host, as defined in RFC 2516, creating PPP links over
Ethernet to services on remote Access Concentrators.
Frame Relay
Frame Relay is a wide area network service, defined by ITU-T (formerly
CCITT), ANSI and vendor standards, to which routers may connect in order to
communicate with one another and exchange data. Frame Relay is one of the
services that you can purchase from a service provider to link several offices
together at high speed. Connections are made via synchronous lines, ISDN
calls or G.703 TDM (Time Division Multiplexing) links.
To configure Frame Relay follow these steps
The following steps are required:
1. Create the Frame Relay interface.
2. Add Static DLCs if required.
3. Add Logical Interfaces if required.
