Adding an IP LPort
An IP LPort must be configured on top of the feeder LPort to allow for a numbered IP
interface. This numbered IP interface is then used by OSPF-TE for TE link bandwidth
advertising between the ATM-MPLS gateway switch and the MPLS LER. Only one IP
interface is allowed on the IP Lport.
To add an IP logical port:
1. Expand the instance node for the UNI/NNI feeder LPort on which you want to add
an IP LPort.
2. Right-click on the IP LPort class node and select Add from the pop-up menu.
The Add IP LPort dialog box appears (Figure 9-16).
Figure 9-16. Add IP Lport Dialog Box
3. Complete the fields in the Add IP LPort dialog box, as described in Table 9-13.
