3. Disable interfaces from
receiving and sending
OSPF packets.
silent-interface
{ interface-type
interface-number
|
all
}
By default, an OSPF interface can
receive and send OSPF packets.
The
silent-interface
command
disables only the interfaces
associated with the current
process rather than other
processes. Multiple OSPF
processes can disable the same
interface from receiving and
sending OSPF packets.
Configuring stub routers
A stub router is used for traffic control. It reports its status as a stub router to neighboring OSPF
routers. The neighboring routers can have a route to the stub router, but they do not use the stub
router to forward data.
Router LSAs from the stub router might contain different link type values. A value of 3 means a link to
a stub network, and the cost of the link will not be changed by default. To set the cost of the link to
65535, specify the include-stub keyword in the stub-router command. A value of 1, 2 or 4 means a
point-to-point link, a link to a transit network, or a virtual link. On such links, a maximum cost value of
65535 is used. Neighbors do not send packets to the stub router as long as they have a route with a
smaller cost.
To configure a router as a stub router:
1. Enter system view.
system-view
N/A
2. Enter OSPF view.

3. Configure the router as
a stub router.

By default, the router is not
configured as a stub router.
A stub router is not related to a
stub area.
Configuring OSPF authentication
Perform this task to configure OSPF area and interface authentication.
OSPF adds the configured key into sent packets, and uses the key to authenticate received packets.
Only packets that pass the authentication can be received. If a packet fails the authentication, the
OSPF neighbor relationship cannot be established.
If you configure OSPF authentication for both an area and an interface in that area, the interface
uses the OSPF authentication configured on it.
Configuring OSPF area authentication
You must configure the same authentication mode and key on all the routers in an area.
To configure OSPF area authentication:
1. Enter system view.
