A device should advertise its directly connected subnets into an interior routing protocol, but those subnets are not being advertised. Which kind of policy addresses that?
選択肢
- An export policy that accepts the directly connected routes for that protocol.
- A firewall filter on the interfaces of those subnets, which allows the routing protocol to include them in its advertisements once the filter has permitted the traffic that belongs to those subnets.
- An import policy that accepts the directly connected routes, so the protocol includes them when it builds its advertisements.
- A change to the preference of the directly connected routes, which is the value the protocol consults when it decides what to advertise.
