Specify the OSPF Tag

By default, no OSPF tag strings are associated with static routes. You can specify an OSPF tag string by including the tag statement at the [edit routing-options static (defaults | route)] hierarchy level (for routing instances, include the statement at the [edit routing-instances routing-instance-name routing-options static (defaults | route)] hierarchy level):

[edit routing-options static (defaults | route)] 

tag string;
