For example, the customer site is assigned the addresses

192.168.1.0/24 through 192.168.1.1/24. The address 192.168.1.1/24 is

also the default gateway for the remote network. The above settings

remove any routing/forwarding intelligence from the CPE. The associ-

ated Cisco configuration will set serial interface (s0) to accommodate

half bridging for the above example.

Authentication is optional under PPP. In a point-to-point leased-

line link, incoming customer facilities are usually fixed in nature, there-

fore authentication is generally not required. If the foreign device

requires authentication via PAP or CHAP, the PPP software will

respond with default Peer-ID consisting of the units Ethernet MAC

address and a password which consists of the unit’s Ethernet MAC

address.

Some networking systems do not define network numbers in pack-

ets sent out over a network. If a packet does not have a specific desti-

nation network number, a router will assume that the packet is set up

for the local segment and will not forward it to any other sub-network.

However, in cases where two devices need to communicate over the

wide-area, bridging can be used to transport non-routable protocols.

Figure 2 illustrates transparent bridging between two routers over

a serial interface (s0). Bridging will occur between the two Ethernet

Interfaces on Router A (e0 and e1) and the two Ethernet Interfaces on

Router B (e0 and e1).

3.1.1 Switch S2

The table below shows the default configurations for Switch S2. A

description of all S2 options follows this table.

Switches S2-1, S2-2, and S2-3

Use Switches S2-1, S2-2 and S2-3 to set the DTE data rate.

Each setting represents an nx56/nx64 setting. Individual channel set-

tings can be configured through the software control port.

S2-1 S2-2 S2-3 Speed

Off Off Off Clear Channel (Unframed)

On Off Off 112kbps/128kbps

Off On Off 224kbps/256kbps

On On Off 336kbps/384kbps

Off Off On 448kbps/512kbps

On Off On 672kbps/768kbps

Off On On 896kbps/1024kbps

On On On 1344kbps/1536kbps

Switch S2-4: Line Framing and Coding

Use Switch S2-4 to control the Network Line Framing and Coding

Options. Set these options to be the same as the Line Framing and

Coding Options given to you by your Service Provider. If you are using

two Model 2720s together as short range modems, set both units iden-

tically.
