RFC1253-MIB

-- Changes to rfc1253 (OSPF MIB):
--      Changed ospfAreaID in index clause for ospfAreaEntry to
--              ospfAreaId.
--      Changed ospfLSACount in definition for sequence OspfAreaEntry
--              to ospfAreaLSACount.
--      Suggestion: the DEFVAL clauses should be removed from
--              the objects that are counters. Some objects that
--              are gauges should probably not have DEFVAL clauses.

     --  OSPF Interface Metric Table

     --      The Metric Table describes the metrics to be advertised
     --      for a specified interface at the various types of service.
     --      As such, this table is an adjunct of the OSPF Interface
     --      Table.

     -- Types of service, as defined by RFC 791, have the ability
     -- to request low delay, high bandwidth, or reliable linkage.

     -- For the purposes of this specification, the measure of
     -- bandwidth

     --      Metric = 10^8 / ifSpeed

     -- is the default value.  For multiple link interfaces, note
     -- that ifSpeed is the sum of the individual link speeds.
     -- This yields a number having the following typical values:

     --      Network Type/bit rate   Metric

     --      >= 100 MBPS                 1
