Description (partial)


When a PPPoE session first comes up, the initial Network Control
Protocol (e.g. IPCP) packet from the remote peer may be discarded,
forcing the peer to time out and retransmit the packet.  This may
cause a slight delay (usually about 2 seconds) in enabling the
session for network layer traffic.


This symptom has been observed when a large number of PPPoE
sessions come up in a short amount of time.
