routing policy is matched, regardless of whether a default route exists in the routing table, and the routing policy modifies some values in the Type-5 LSA. type type: Specifies a type for the Type-5 LSA: 1 or 2. If type is not specified, the default type for the Type-5 LSA specified by the default type command applies. summary: Advertises the Type-3 summary LSA of the specified default route. Description Use default-route-advertise to generate a default route into the OSPF routing domain. Use undo default-route-advertise to disable OSPF from distributing a default external route. By default, no default route is distributed. The default-route-advertise summary cost command is applicable only to VPNs, and the default route is redistributed in a Type-3 LSA. The PE router advertises the redistributed default route to the CE router. Using the import-route command cannot redistribute a default route. To redistribute a default route, use the default-route-advertise command. If neither the always nor permit-calculate-other keyword is specified, the router generates a default route in a Type-5 LSA into the OSPF routing domain only when an active default route that does not belong to the current OSPF process exists in the IP routing table. The router then does not calculate default routes from other routers. Related commands: import-route and default.

is not specified, the default type for the
Type-5 LSA specified by the

command applies.
summary
: Advertises the Type-3 summary LSA of the specified default route.
Description
Use
default-route-advertise
to generate a default route into the OSPF routing domain.
Use
undo default-route-advertise
to disable OSPF from distributing a default external route.
By default, no default route is distributed.
The
default-route-advertise
summary cost
command is applicable only to VPNs, and the default route is
redistributed in a Type-3 LSA. The PE router advertises the redistributed default route to the CE router.
Using the

the
default-route-advertise
command.
If neither the

nor
permit-calculate-other
keyword is specified, the router generates a default route
in a Type-5 LSA into the OSPF routing domain only when an active default route that does not belong to
the current OSPF process exists in the IP routing table. The router then does not calculate default routes
from other routers.
