R211x-HP Flexfabric 11900 Layer 3 - IP Routing Command Reference

177
Parameters
router-id: Specifies the router ID, in the format of an IPv4 address.
Usage guidelines
OSPF uses a router ID to identify a device. If no router ID is specified, the global router ID is used.
If no global router ID is configured, the highest loopback interface IP address is used as the router ID. If
no loopback interface IP address is available, the highest physical interface IP address is used,
regardless of the interface status (up or down).
During an active/standby switchover, the new active main processing unit (MPU) checks whether the
previously backed up router ID is valid. If not, it selects a new router ID.
A new router ID is selected only when the interface IP address used as the router ID is removed or
changed. Other events will not trigger a router ID re-selection. For example, router ID re-selection is not
triggered when the interface goes down, you change the router ID to the address of a loopback interface
after a physical interface address is selected as the router ID, or a higher interface IP address is
configured as the router ID.
After a router ID is changed, you must use the reset command to enable it.
Examples

silent-interface (OSPF view)
Use silent-interface to disable an interface or all interfaces from receiving and sending OSPF packets.
Use undo silent-interface to remove the configuration.
Syntax
silent-interface { interface-type interface-number | all }
undo silent-interface { interface-type interface-number | all }
Default
An interface can receive and send OSPF packets.
Views
OSPF view
Predefined user roles
network-admin
mdc-admin
Parameters
interface-type interface-number: Specifies an interface by its type and number.
all: Specifies all interfaces.
Usage guidelines
A disabled interface is a passive interface that cannot receive or send any hello packets.
