Hi
i am obeserving a Latency in Satelite Link , if the LINK Latency is 1000ms then PPP link comes UP if the LINK latency increases to 1.5sec then PPP negotiation comes up after 2 or 3min or some time never comes UP
If Link Latency increases to 2sec then negotitation never comes UP.
debugs are shown below would like to have input what could be the reason or is there any timeout period for CONFREQ msg ..
because i am seeing CONFREQ msg ID same but PPP has alread declared "CP_CONFACK does not match CP_CONFREQ"
is latency has anything to with PPP initial negotiation what should be idel timeframe for negotiation process to complete .
when i change to HDLC link never flaps because there is no negotiation process in it as per HDLC debug ..
looking for input
Below is Satalite LINK output when latency is 2sec
