PPP or Frame Relay:

The layer two protocol used to transfer

packets can be PPP or Frame Relay (RFC 1490). PPP allows a
point-to-point connection, whereas Frame Relay can provide up
to ten permanent virtual circuits.

Routing and Bridging with the Express 6100/
6120

The Express 6100/6120 is a Router and Transparent Learning Bridge.
Its features can be easily configured and used once several basic con-
cepts are understood.

Factory Default

The Express 6100/6120 comes from the factory configured for MAC
Bridging with no filters or connection information defined. An IP ad-
dress of 10.0.0.1 with a network mask of 255.255.255.0 is preloaded.
The factory default layer two configuration is Auto Detect, which au-
tomatically detects PPP or Frame Relay.

Bridging

In Bridge Mode, the Express 6100/6120 can be used to connect two
LAN segments. In this mode, all protocols are supported because they
are transported across the IDSL link at the MAC layer. The Spanning
Tree Algorithm can be used to guarantee a loop-free topology. MAC
addresses are “learned” by each Express 6100/6120 to prevent non-
WAN packets from being bridged.

IP Routing

The Express 6100/6120 operates as an IP router when the

Configura-

tion/IP/IP Router/Mode

option is configured to

On

. In PPP mode, the

Express 6100/6120 uses an IP unnumbered WAN interface; the IP ad-
dress and mask assigned to the unit’s LAN interface apply to all rout-
ing and IP operations for the unit. In Frame Relay mode, each PVC
can be specified as numbered or unnumbered links. If a default gate-
way is specified on the network of the Ethernet interface, the unit at-
tempts to reach the gateway through that interface. If no default
gateway is specified (i.e., 0.0.0.0) the WAN interface becomes the de-
