Associate a network with a previously created shared network object. To associate a network with a shared network object: From the configuration drop-down menu, select a configuration. Select the IP Space tab. Tabs remember the page you last worked on, so select the tab again to ensure you're on the Configuration information page. Under IPv4 Blocks, click an IPv4 block. Under Blocks and Networks, click an IPv4 network. Click the network name and select Share (Share isn't available until you associate an object tag with a configuration). Select a tag from the list and click Add. Repeat this procedure for additional networks.
