Configuration Guide - IP Unicast Routing

S7700 and S9700 V200R011C10

This document describes IP Unicast Routing configurations supported by the switch, including the principle and configuration procedures of IP Routing Overview, Static Route, RIP, RIPng, OSPF, OSPFv3, IS-IS(IPv4), IS-IS(IPv6), BGP, Routing Policy ,and PBR, and provides configuration examples.

Configuring a DR Priority for an Interface

Configuring a DR Priority for an Interface


The DR priority on a switch interface determines whether the interface is qualified for the DR election. If the DR priority is 0, the switch cannot be elected as a DR or BDR.

Perform the following operations on the switch that runs OSPFv3.


  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. (Optional) On an Ethernet interface, run undo portswitch

    The interface is switched to Layer 3 mode.

    By default, an Ethernet interface works in Layer 2 mode.

  4. Run ospfv3 dr-priority priority [ instance instance-id ]

    A DR priority is set for the interface.

Follow-up Procedure

After the DR priority is changed, you can re-elect a DR or BDR. However, this will interrupt OSPFv3 neighbor relationships between switches and is therefore only used when necessary. The methods to re-elect a DR or BDR are as follows:

  • Restart all switches.

  • Run the shutdown and undo shutdown commands on the interface on which the OSPFv3 neighbor relationship is set up.
