Configuring a Logical Port for Layer 2 VPN
To implement VPN for a network that contains SVCs, specify the net overflow
attribute when you configure a UNI logical port (see Table 3-3 on page 3-21). This
parameter determines whether SVCs originating from this port are restricted to trunks
of their own VPN, or whether SVCs can use public (shared) trunks during overflow
conditions.
Once you configure a logical port, use the following steps to dedicate it to a VPN and
customer name:
1. Right-click on the instance node of the LPort to which you want to assign a
Layer 2 VPN and customer name.
2. Select L2 VPN/Customer Info from the pop-up menu. The Choose VPN/Policy
dialog box appears (Figure 13-5).
Figure 13-5. Choose VPN/Policy Dialog Box
3. In the Customer Name field, select the customer name you want to assign to this
LPort.
4. In the VPN/Policy Name field, select the VPN or policy name you want to assign
to this LPort.
5. Choose OK.
