Configuring ISG Access for PPP Sessions: Example
The following example shows the configuration of an ISG policy that provides services to PPP
subscribers. This example configures ISG to perform the following actions:
• PPP local termination
ISG will provide local termination by activating the service “ispa” for subscribers matching the
domain “ispa”. The system will authenticate the subscriber using method-list “list1”. For local
termination services, the global VRF is applied by default unless another VRF is specified in the
service profile, on the interface, or in the virtual template.
• PPP authentication before forwarding
ISG will locally authenticate subscribers matching domain “ispb” before forwarding the sessions to
an LNS. (Sessions are forwarded to an LNS because service policy map “ispb” specifies a VPDN
group). The system will authenticate the subscribers using method-list “list2”.
• PPP forwarding without local authentication
ISG will forward sessions to an LNS without local authentication for subscribers matching domain
“ispc”.
• PPP domain exclusion
