No, the `tag is just a number you add to a route to allow you to do certain
route manipulation. Below is an example of two routes redistributed into
ospf which are tagged.
The tag now allows you to match the routes. For example if you redistribute
from ospf to rip you may chose to deny or permit those tagged routes, set
the metric etc...
