--  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
--      Ethernet/802.3             10

--      E1                         48
