Configuring Dr Priority Of An Interface - Huawei S6700 Series Configuration Manual

S6700 Series Ethernet Switches
Configuration Guide - IP Routing
The interface is suppressed from sending and receiving OSPFv3 packets.
----End
Follow-up Procedure
Different processes can suppress the same interface from sending and receiving OSPFv3 packets,
but the silent-interface command is valid only for the OSPFv3 interface on which the specified
process is enabled, and does not take effect on the interface of other processes.
After an OSPFv3 interface is set to be silent, the interface can still advertise its direct routes
through the Intra-Area-Prefix-LSA of the same router. No OSPFv3 neighbor relationship can
be set up on the interface. Therefore, the OSPFv3 adaptability is enhanced.

5.9.4 Configuring DR Priority of an Interface

When configuring a broadcast network or an NBMA network, you can specify the DR priority
for each interface to change the results of DR/BDR election on the network.
Context
The DR priority on a switch interface qualifies the interface for the DR election. If the DR priority
is 0, the switch cannot be elected as a DR or BDR.
Do as follows on the switch that runs OSPFv3.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface vlanif interface-number
The interface view is displayed.
Step 3 Run:
ospfv3 dr-priority priority [ instance instance-id ]
The DR priority of the interface is set.
----End
Follow-up Procedure
After the DR priority is changed, you can re-elect a DR or BDR through the following methods,
which, however, will result in the interruption of the OSPFv3 neighbor relationship between
switches and therefore are used only when necessary.
