>Environment:
FreeBSD connected to cisco 2511 with 57600 async LL

	The condifuration is pretty much usual.  Some recent
	version of PPP (pre-2.2.2) worked well and still does.

>Description:

	Permanent PPP LL connection starts form /etc/start_if.tun0
	but the problem occurs after manual dial as well.

	After a carrier drop PPP doesn't redial, log shows
	that it goes to a state when the last 3 messages
	in the log are:

... LCP: State change Req-Sent --> Stopped
... LCP: LcpLayerFinish
... Phase: NewPhase: Dead

	... and it just sits there forever.

	If I telnet 127.0.0.1 3000 then after a few different "show"
	commands I noticed that redial timer (is set to 5 seconds
	and 999 attempts) is not decremented, PPP just sits at
	"3 seconds remained until a redial attempt" or alike.

	"3 seconds" aren't changing.

>How-To-Repeat:

	I think that just launch /usr/bin/ppp -ddial to something
	which speaks PPP, and wait (or provoce) a carrier drop
	or line disconnect.

	I did this a few times with identical results.

>Fix:
	
	Considering the fact that recently some changes
	were applied to PPP, I think that some damage was
	done to PPP state machine with regard to redialing,
	it worked in pre-2.2.2 days.

	Nothing more detailed, sorry. The testbed is here
	and I'm ready to do any test and actions one would
	like me to do in order to discover problem source.
