Change the metric added to DVMRP routes advertised in incoming

The keywords have these meanings:
• (Optional) in—Specifies that the increment value is added to
incoming DVMRP reports and is reported in mrinfo replies.
• (Optional) out—Specifies that the increment value is added to
outgoing DVMRP reports for routes from the DVMRP routing
table.
If neither in nor out is specified, in is the default.
For increment, specify the value that is added to the metric of a DVMRP
router advertised in a report message. The range is 1 to 31.
If the ip dvmrp metric-offset command is not configured on an
interface, the default increment value for incoming routes is 1, and the
default for outgoing routes is 0.
