Description
Use the
filter-policy export
command to configure the filtering of outgoing redistributed routes.
Use the
undo filter-policy export
command to disable such filtering.
By default, filtering of outgoing redistributed routes is not configured.
In some cases, it may be required that only the routing information meeting some conditions can be
advertised. You can use the
filter-policy
command to set the filtering conditions for the routing
information to be advertised. Only the routing information passing the filtration can be advertised.
This command filters routes redistributed (with the
import-route
command) by OSPF. If the
protocol
argument is specified, this command filters only the outgoing routes redistributed from the protocol. If
the
protocol
argument is not specified, the outgoing routes redistributed from all protocols will be
filtered.
