Controlling Advertising and Processing in Routing Updates
You can use the distribute-list router configuration command with access control lists to suppress routes
from being advertised in routing updates and to prevent other routers from learning one or more routes. When
used in OSPF, this feature applies to only external routes, and you cannot specify an interface name.
You can also use a distribute-list router configuration command to avoid processing certain routes listed in
incoming updates. (This feature does not apply to OSPF.)
