I created a Config Change Template, selected the nodes I wanted to remove/add IP Helper to, selected the interfaces on the nodes and executed. See Below
script AddIPHelperAddress (
NCM.Nodes @ContextNode, NCM.Interfaces[] @Interfaces, string @NewIPHelper, string @OldIPHelper)
{
CLI
{
}
foreach (@itf in @Interfaces)
{
CLI
{
config t
interface @itf.InterfaceDescription
no ip helper-address @OldIPHelper
ip helper-address @NewIPHelper
quit
}
}
CLI {quit}
}
