Configuring PNNI Routing
PNNI Policy-based Routing
There are three types of links that can be established with policy-based routing:
• Untagged – This link can only be used by a non-policy constrained call.
• Tagged, with Bare Resources – VPN call with private net overflow set to public.
This link may also be used by non-policy constrained calls.
• Fully Tagged – Can only be used by a policy-based routed call, either public or
restricted. If this link is not available, the call will try to be routed through the
public VPN.
To configure policy-based circuits:
1. In the switch object tree tab in the Navigation Panel, expand the circuits class
node and double-click on the PVC class node on which you want to configure the
PNNI policy.
2. Select a circuit from the list, then right-click on it.
3. From the pull-down menu, choose L2 VPN/Customer Info. The Choose
VPN/Policy dialog box appears (Figure 21-12).
Figure 21-12. Choose VPN/Policy Dialog Box
4. Select a customer name from the Customer Name list.
5. Select a policy name from the VPN/Policy Name list (includes policies for
policy-based circuits as well as the Layer 2 VPNs).
6. Choose OK.
Note – The steps to configure policy-based PVCs and SPVCs are very similar. The
steps below use PVCs as an example.
