<sect1>Attributes
<p>OSPF defines three route attributes. Each internal route has a metric. External
routes use metric type 1 or metric type 2. A metric of type 1 is comparable
with internal metrics, a metric of type 2 is always longer than any metric of type 1
or any internal metric. Each external route can also carry a tag which is
a 32-bit integer which is used when exporting routes to other protocols; otherwise,
it doesn't affect routing inside the OSPF domain at all.
<p>OSPF defines three route attributes. Each internal route has a <cf/metric/
Metric is ranging from 1 to infinity (65535).
External routes use <cf/metric type 1/ or <cf/metric type 2/.
A <cf/metric of type 1/ is comparable with internal <cf/metric/, a
<cf/metric of type 2/ is always longer
than any <cf/metric of type 1/ or any <cf/internal metric/.
Each external route can also carry a <cf/tag/ which is a 32-bit
