The following items are displayed on this page:
◆
Default Route Selection
– Enables the default route to be specified or
selected automatically.
◆
VPI
(Virtual Path Identifier) – A grouping of virtual channels which
connect the same end-points, and which share a traffic allocation.

Encapsulation:
■
LLC
(Logical Link Control) – This encapsulation method allows
multiplexing of multiple protocols over a single ATM virtual
connection. In some cases, the LLC header is followed by a SNAP
header which uniquely identifies a routed or bridged protocol. (This
is the default packet encapsulation format used for carrying IP
datagrams over AAL5 ATM.)
