Configuring OSPF to redistribute a default route
Using the import-route command cannot redistribute a default external route. To do so, you must use the
default-route-advertise command.

Not redistributed by default.
The default-route-advertise
summary cost command is
applicable only to VPN, and
the default route is
redistributed in a Type-3 LSA.
The PE router advertises the
default route to the CE router.
Configuring the default parameters for redistributed routes
You can configure default parameters, such as the cost, upper limit, tag and type for redistributed routes.
Tags indicate information related to protocols. For example, when redistributing BGP routes, OSPF uses
tags to identify AS IDs.
