Because multiple dynamic routing protocols could be running on a router, there is the
problem of routing information sharing among routing protocols and selection.
Therefore, a default preference is specified for each routing protocol. When a route is
identified by different protocols, the protocol with a high preference will play a decisive
role.
Example
# Specify the preference of an imported external route of the AS as 160.
[Quidway-ospf-1] preference ase 160
3.1.49 reset ospf
Syntax
reset ospf [ statistics ] { all | process-id }
View
User view
Parameter
statistics : Resets OSPF statistics.
all : Resets all OSPF processes.
process-id : ID of an OSPF process. If no OSPF process is specified, all OSPF
processes are reset.
Description
Use the reset ospf all command to reset all OSPF processes.
Use the reset ospf process-id command to reset the corresponding OSPF process.
The following are the benefits of the reset ospf all command:
z
Clear invalid LSA immediately without waiting for LSA timeout.
z
If the Router ID changes, a new Router ID will take effect by executing the
command.
z
Re-elect DR and BDR conveniently.
z
OSPF configuration before the restart will not lose.
The system will require the user to confirm whether to re-enable the OSPF protocol
after execution of the command.
Example
# Reset all the OSPF processes.
<Quidway> reset ospf all
# Reset OSPF process 200.
