Multiservice Interface Model
For a subscriber without a static VPN configuration, a multiservice interface must be configured on the
ISG device to map the IP session to a VRF. The multiservice interface represents a boundary between a
VPN routing domain and the default routing domain. In cases where an IP subscriber may be associated
with several routing domains throughout the duration of a connection, multiservice interfaces serve as
demarcation points for the IP subscriber to switch from one VPN domain to another.
Figure 3
illustrates
the multiservice interface model.
