4-7
summary
: Advertises the Type-3 summary LSA of the specified default route.
Description
Use the
default-route-advertise
command to generate a default route into the OSPF routing domain.
Use the
undo default-route-advertise
command to disable OSPF from distributing a default external
route.
By default, no default route is distributed.
Using the
import-route
command cannot redistribute a default route. To do so, use the
default-route-advertise
command. If no default route exists in the router's routing table, use the
default-route-advertise always
command to generate a default route in a Type-5 LSA.
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.
