Configuring PNNI Routing
Enabling Name LSA Flooding on the Switch
To enable Lucent switches to use PNNI routing or to interoperate with PNNI switches
in your network, you must enable the flooding of Name link state advertisements
(LSAs) on the switch. Lucent switches flood NAME(3) and SUMM_NM(3) type
LSAs over the VNN trunk interfaces. These LSAs bind the VNN switch IP address to
an ATM address so that the PNNI and VNN switches can communicate.
To enable Name LSA flooding on a CBX 3500, CBX 500, or GX 550 switch:
1. Expand the network node where the switch resides.
2. Expand the Switches class node.
3. Right-click on the switch node and select Modify from the pop-up menu. The
Modify Switch dialog box appears (Figure 21-5 on page 21-23).
4. Select the PNNI Name Translation check box to enable flooding of NAME(3) and
SUMM_NM(3) LSAs for this switch.
5. Choose OK to save your changes and close the Modify Switch dialog box.
For more information about configuring Name LSA flooding for VNN OSPF, see
Chapter 7, “Configuring Trunks.”
Note – You must enable the PNNI Name Translation field if the switch uses PNNI
routing or interoperates with other PNNI switches in your network.
