Have you reviewed App Note 41? It seems related to the scenario you’re describing.

Yes, i saw document. But, as you see in event log.
While changing ip address

21:41:57, 20 Feb 2016,Default Route 0 Out Of Service,Activation
21:41:57, 20 Feb 2016,PPP 0 Out Of Service,Activation
21:41:57, 20 Feb 2016,PPP 0 down,Remote disconnect
21:41:57, 20 Feb 2016,PPPOE 0 PPP Session Terminated,Remote request

and then after 1 second PPP 1 interface is up.
I dont want to be up immediately. I want to achive to not be started while changign ip address on PPP 0 interface.

as you see ppp 0 interface is started again after 8 seconds.

where is option for achieving that?

if you have PPP 1 in advanced configuration inhibit its self if PPP 0 is “‘active and not OOS’”

tin PPP 0 advanced configuration there is a setting

"If this PPP interface gets disconnected, allow it to attempt to reconnect times before allowing other PPP interface inhibited by this interface to connect "

set this to 1

this should keep PPP 1 down while PPP 0 has 1 attempt to reconnect after that attempt PPP 1 will come up

i put configuration as you instruct, it doesnt work. it always brig up ppp1 while changig isp ip on ppp0.

maybe problem is in this. when i put in advanced on ppp 1 “Inhibit this PPP interface if the following PPP instances 0 “active and not OOS”” it’s dont remember that it show only “Active”. whay it doesnt remember my configuration when i put “active and not OOS”.
