186 SmartSwitch Router User Reference Manual
It is only possible to restrict the importation of OSPF ASE routes when functioning as an
AS border router.
Like the other interior protocols, preference cannot be used to choose between OSPF ASE
routes. That is done by the OSPF costs. Routes that are rejected by policy are stored in the
table with a negative preference.
For all examples in this section, refer to the configuration shown in Figure 18 on page 187 .
