All examples use comma as the separator. You can use other supported separators, such as semicolon, space, or tab. # Adding an IPv4 Shared Network This example shows how to import a new shared Network in the Default DHCP view. `header-SharedNetwork,name*,networks*,network_view,comment,OPTION-2 SharedNetwork,Sharednetwork01,"10.0.0.0/24,20.0.0.0/24",Default,This is a comment.,128` # Overwriting IPv4 Shared Network Data This example shows how to overwrite a shared network with additional networks. `header-SharedNetwork,name*,networks* SharedNetwork,Sharednetwork01,"10.0.0.0/24,20.0.0.0/24,30.0.0.0/24"` # Merging IPv4 Shared Network Data This example shows how to merge the extensible attribute Site and a new admin group DHCP_admins with RW permission to an IPv4 shared network. `header-SharedNetwork,name*,networks*,EA-Site,ADMGRP-DHCP_admins SharedNetwork,Sharednetwork01,"10.0.0.0/24,20.0.0.0/24",USA,RW`
