Could someone please help me understand how I could loop through the following nodes definition in my templates file?

ip::addr{ "as2s67v":
    ip0 => "192.168.30.0",
    pre0 => "/24",
    ip1 => "172.45.35.0",
    pre1 => "/16",
    ip2 => "145.88.88.0",
    pre2 => "/24",
}

I'd like to print out the above using my template file, however I can't be certain of how many entries will exist, I want to end up with a file like so:

server: as2s67v
ipaddress0 = "192.168.30.0"
prefix0 = "24"
ipaddress1 = "172.45.35.0"
prefix1 = "16"
ipaddress2 = "145.88.88.0"
prefix2 = "24"

How could I go about achieving this?

thanks Dan

Not exactly what you're looking for, but it cuts down on having to keep multiple variables in sync:

site.pp:

class { 'ip::addr':
  name  => "as2s67v",
  cidrs => [ "192.168.30.0/24", "172.45.35.0/16", "145.88.88.0/24" ]
}

modules/ip/addr.pp:

class ip::addr ($cidrs) {
  file { "/tmp/$name":
    content => template("ip/template.pp")
  }
}

template.pp:

server: <%= name %>
<% for idx in (0..(cidrs.length-1)) -%>
ipaddress<%= idx %> = "<%= cidrs[idx].split("/")[0] %>"
prefix<%= idx %> = "<%= cidrs[idx].split("/")[1] %>
<% end -%>
