PROTOCOL SPECIFICATION AND TEST SETUP

ANVL Test Suite PPP Family (ppp of ppp, pppauth, rfc1471, rfc1473)

RFC 1661:  'The Point-to-Point Protocol (PPP)'

(William Allen Simpson, Daydreamer, July 1994)

RFC 1662:  'PPP in HDLC-like Framing'

(William Allen Simpson, Daydreamer, July 1994)

This test suite requires that the workstation running ANVL be

connected to the DUT with a serial cable. The DUT should be

configured to have all default values for its options. Some

tests require LQM, IP (if available in this version of ANVL) or

a LAN interface to also be configured.
