By default, no default route is
redistributed.
This command is applicable
only to VPNs. The PE router
advertises a default route in a
Type-3 LSA to a CE router.
Configuring default parameters for redistributed routes
Perform this task to configure default parameters for redistributed routes, including cost, tag, and type.
Tags indicate information about protocols. For example, when redistributing BGP routes, OSPF uses tags
to identify AS IDs.
To configure the default parameters for redistributed routes:
