Optional
By default, the maximum interval is 5
seconds, the minimum interval is 0
milliseconds and the incremental
interval is 5000 milliseconds.
NOTE:

incremental-interval × 2
n-2
(n is the
number of generation times) each time a LSA generation occurs until the
maximum-interval is reached.
Disabling interfaces from sending OSPF packets

silent-interface { interface-type
interface-number | all }
Optional
Not disabled by default
NOTE:
• Different OSPF processes can disable the same interface from sending OSPF packets. Use of the
silent-interface command disables only the interfaces associated with the current process rather than
interfaces associated with other processes.
• After an OSPF interface is set to “silent”, other interfaces on the router can still advertise direct routes of
the interface in Router LSAs, but the interface cannot send any packet. This confi
g
uration can enhance
OSPF networking adaptability and reduce resource consumption.
Configuring stub routers
A stub router is used for traffic control. It tells other OSPF routers to not use it to forward data.
The Router LSAs from the stub router may 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. 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.
Thus, neighbors find that the links to the stub router have such big costs that they will not send packets to
the stub router for forwarding as long as another route with a smaller cost exists.
Follow these steps to configure a router as a stub router:
