The Encapsulation Mode is related to the VPI and VCI numbers,

which are specified by your service provider (see Permanent VC
Settings, page 18).

Supplied by your service provider (reference table
appears on page 5).

Your Bridge choices are related to the Encapsulation Mode (see

above). Note: You must enable Bridge if your service provider is

using Bridged IP LLC or VCMUX (RFC 1483) Encapsulation.

IGMP is the Internet standard for IP multicasting, or broadcasting
a message to many recipients simultaneously. Your choices are
enabled or disabled; the default is disabled.

Before enabling IGMP, navigate to the Advanced Setup

page, click Misc Configuration, select Enabled in the

IGMP Proxy dropdown list, and click Save Changes and

Write Settings to Flash and Reboot. If you don’t

perform this step first, enabling IGMP on this page will
not have any effect.

Normally, you would not enter anything into the Default Gateway
field. You would do so only if you want to connect your modem to

the Internet via a different Gateway Router, or if your service

provider has instructed you to change it.

PPP is the most widely used protocol for authenticating your
connection to the Internet. Should you change service providers,

you may need to change the data in these fields. Note: These

settings also appear on your Basic Settings page.
