Click Apply.

Each time you click Apply after entering a DLCI, a new logical interface appears in the Interface column. The DLCI entry field remains blank to allow you to add more frame relay logical interfaces.

14.Click the logical interface name in the Interface column of the Logical Interfaces table to go to the Interface page.

15.Enter the IP address for the local end of the PVC in the Local address text box.

16.Enter the IP address of the remote end of the PVC in the Remote address text box. Click Apply.

17.(Optional) Change the interface’s logical name to a more meaningful one by typing the preferred name in the Logical name text box.

Unnumbered Interfaces

Traditionally, each network interface on an IP host or router has its own IP address. This situation can cause inefficient use of the scarce IP address space because every point-to-point link must be allocated an IP network prefix. To solve this problem, a number of people have proposed and implemented the concept of unnumbered point-to-point lines. An unnumbered point-to-point line does not have any network prefix associated with it. As a consequence, the network interfaces connected to an unnumbered point-to-point line do not have IP addresses. Whenever the unnumbered interface generates a packet, it uses the address of the interface that the user has specified as the source address of the IP packet. Thus, for a router to have an unnumbered interface, it must have at least one IP address assigned to it.

The Nokia implementation of Unnumbered Interfaces supports OSPF (Open Shortest Path First) and Static Routes only. Virtual links are not supported.

Configuring Unnumbered Interfaces

To configure an unnumbered interface

1.Click Interfaces under Configuration > Interface Configuration in the tree view.

2.Click the logical interface link to configure in the Logical column. Example: atm s3p1c1.
