Default Route Policy Actions

Routing protocols have default behaviors for the import and export of routing information.
For BGP, OSPF, and IS-IS, the default route policy actions are as follows:
7705 SAR OS Router Configuration Guide
• BGP
→ import – all routes from BGP peers are accepted and passed to the BGP route
selection process
→ export (internal routes) – all active BGP routes are advertised to BGP peers
→ export (external routes) – all non-BGP learned routes are not advertised to BGP
peers
• OSPF and IS-IS
→ import – not applicable; all OSPF or IS-IS routes are accepted from OSPF or
IS-IS neighbors and cannot be controlled by route policies
→ export (internal routes) – all OSPF or IS-IS routes are automatically advertised
to all neighbors
→ export (external routes) – all non-OSPF or non-IS-IS learned routes are not
advertised to OSPF or IS-IS neighbors
