In the network application,from one Moto router dial to quidway2620 with ISDN line.But it can't work well.The connect of the two router can be established normaly use DDR,but from the Moto router,can't ping though to quidway2620,on Moto router,there is no route to 2620,though the dailer interfaces of the two router are in the same sub-net.
Change the IPCP option parameter of Moto from VJ to ADDR,from Moto can ping 2620 normaly

Above is the configuration of Moto router,you can check the IPCP option parameter,in quidway router,we didn't support VJ mode,so on the procedure of the PPP negotiate,Moto and quidway can't negotiate a correct attribute of the IP address,of course on the two router they can't get the right route to each other.
