R2511-HP MSR Router Series Layer 3 - IP Routing Command Reference(V5)

126
If no global router ID is configured, the highest loopback interface IP address, if any, 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.
During an active/standby switchover, the standby main board checks whether the previous router ID that
is backed up before switchover is valid. If not, it selects a new router ID.
If the interface whose IP address is the router ID is removed or modified, a new router ID is selected.
Other events, (the interface goes down; after a physical interface address is selected as the router ID, an
IP address is configured for a loopback interface; a higher interface IP address is configured) will not
trigger a router ID re-selection.
After a router ID is changed, use the reset ospf process command to make it effective.
Examples
# Configure a global router ID.
<Sysname> system-view
[Sysname] router id 1.1.1.1
silent-interface (OSPF view)
Use silent-interface to disable an interface or all interfaces from r sending OSPF packets.
Use undo silent-interface to restore the default.
Syntax
silent-interface { interface-type interface-number | all }
undo silent-interface { interface-type interface-number | all }
Default
An interface can send OSPF packets.
Views
OSPF view
Default command level
2: System level
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 send any hello packets.
To disable a network from receiving OSPF routes, you can issue this command on the interface
connected to the network.
Examples
# Disable an interface from sending OSPF packets.
<Sysname> system-view
[Sysname] ospf 100
[Sysname-ospf-100] silent-interface ethernet 1/1
