18.3.13 Export Policies Example: Exporting to OSPF
It is not possible to create OSPF intra- or inter-area routes by exporting routes from the RS routing table into OSPF. It
is only possible to export from the RS routing table into OSPF ASE routes. It is also not possible to control the
propagation of OSPF routes within the OSPF protocol.
There are two types of OSPF ASE routes: type 1 and type 2. The default type is specified by the
ospf set
ase-defaults type 1/2
command. This may be overridden by a specification in the
ip-router policy create
ospf-export-destination
command.
OSPF ASE routes also have the provision to carry a tag. This is an arbitrary 32-bit number that can be used on OSPF
routers to filter routing information. The default tag is specified by the
ospf set ase-defaults tag
command.
This may be overridden by a tag specified with the
ip-router policy create ospf-export-destination
command.
Interface routes are not automatically exported into OSPF. They have to be explicitly done.
