OSPFv2 distribute list

A distribution list can be configured to explicitly deny specific routes from being eligible for installation in the IP route table. By default, all OSPFv2 routes in the OSPFv2 route table are eligible for installation in the IP route table. Receipt of LSAs are not blocked for the denied routes. The device still receives the routes and installs them in the OSPFv2 database. The denied OSPFv2 routes cannot be installed into the IP route table.

The OSPFv2 distribution list can be managed using ACLs or route maps to identify routes to be denied as described in the following sections:
