import
Syntax import policy-name [policy-name...(upto 5 max)]
no import
Context config>service>vprn>ospf
Description This command specifies the import route policy to be used to determine which routes are accepted
from peers. Route policies are configured in the config>router>policy-options context.
This configuration parameter can be set at three levels: global level (applies to all peers), group level
(applies to all peers in peer-group) or neighbor level (only applies to specified peer). The most
specific level is used.
When multiple policy names are specified, the policies are evaluated in the order they are specified. A
maximum of five (5) policy names can be specified. The first policy that matches is applied.
When multiple import commands are issued, the last command entered will override the previous
command.
The no form of the command removes the policy association. To remove the association of all
policies, use no import without any arguments.
