RFC 1577
: Specifies whether the IPoA protocol to be used
complies with the IEFT specification named "RFC 1577 -
Classical IP and ARP over ATM" (contact your ISP if
unsure).
Lower interface
: An IPoA interface must be associated
with one or more ATM VCs that have been defined on the
system. The ATM VC is also considered an interface--one
that performs "lower level" functions (i.e., closer to
hardware) than the IPoA interface. See Configuring the
ATM VC for information about ATM VC interfaces.
Gateway Address
: The external IP address that the
ADSL/Ethernet router communicates with via the IPoA
interface to gain access to the Internet. This is typically an
ISP server.
