Hello Adhi,

when you use any form of advanced DDR or virtual DDR that employs a virtual-template or a dialer the virtual-access is a dynamic interface that inherits some charasteristics from the logical interface and uses some physical resources (like B channels on a ISDN PRI or a ethernet or FE when using PPPoE client)


During the PPP session it is the Virtual-Access that gets the IP address in the IPCP negotiation.

When the PPP session terminates the virtual-access is removed as needed.


see the following link

Hope to help

Giuseppe
