RE: Route Tagging with Default Route

Hi Muzammil,

I tried with "default-information originate route-map tag" And the tag
sticks.

Here is my theory:

The trigger for the tag withdrawal seems to be the default refresh,
indicated by this output from debug ip routing: " RT: NET-RED 0.0.0.0/0"

With default-information originate, this refresh did not cause a withdrawal
of the tag. Perhaps the refresh causes RIP to see the redistributed route
as internal, and it is resent as a new route, without the tag?
