Disabling Interfaces From Receiving And Sending Ospf Packets; Configuring Stub Routers - HP MSR2000 series Configuration Manual

Step
1. Enter system view.
2. Enter OSPF view.
3. Configure the LSA
generation interval.

Disabling interfaces from receiving and sending OSPF packets

Follow these guidelines when you disable interfaces from receiving and sending OSPF packets:
Different OSPF processes can disable the same interface from receiving and sending OSPF packets.
•
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 advertise direct routes of
the interface in Router LSAs, but the interface cannot send any packet. This configuration can
enhance OSPF adaptability and reduce resource consumption.
To disable interfaces from receiving and sending routing information:
Step
1. Enter system view.
2. Enter OSPF view.
3. Disable interfaces from
receiving and sending
OSPF packets.

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 large costs that they will not send packets to the
stub router for forwarding as long as another route with a smaller cost exists.
To configure a router as a stub router:
Step
1. Enter system view.
2. Enter OSPF view.
