That is a hidden command. I found it is not working as it should.
Anyone success?

Re: Doing the solution using some other way
--- Early posted ----------------------
Please see CSCdk41691.
There is a knob in the ios, if you would like to
prefer inter area routes over intra .
This is a hidden configuration option to set the
highest allowed metric that will be installed for an
ospf intra-area route. By default, the highest allowed
intra-area metric is 16777214.
For example, if max-metric is set to 50000, then any
ospf intra-area routes with a metric greater than
50000 will not be installed in the IP routing table.
router ospf <tag>
max-metric intra-area <n>
Where n can range from 1 to 16777214
Adding or deleting this configuration will
automatically cause ospf to re-run the spf
calculation.
To remove the configuration:
router ospf <tag>
no max-metric
The drawback of this approach is if you prefer
inter-area routes, your intra-area routes will not be
used, even when available and you will loose
redundancy.
