Trying this approach I get "Detail: undefined method `each_pair' for
#<Array:0x7f19bc81d288>" using this code:
<% if (@ospfconfig.is_a?(Hash)) and (@ospfconfig.count > 0) -%>
<% @ospfconfig.sort.each do |instance,instparam| -%>
protocol ospf <%= instance %> {
}
<% end -%>
<% end -%>
Can it be a Ruby version thing?
