Disable Helper Mode for OSPFv3

Before you begin

You configure OSPF on a VRF instance the same way you configure the GlobalRouter, except that you must use VRF Router configuration mode and replace ipv6 with ipv6 ospf.

About this task

By default, OSPF Helper mode is enabled when OSPF is configured. You can disable helper mode by the following command and re-enable it again by using “no” or “default” commands.

Procedure

Enter OSPF Router Configuration mode:

enable

configure terminal

router ospf
Enter the following command to disable Helper mode:

ipv6 helper-mode-disable
Enter the following command to enable Helper mode:

no ipv6 helper-mode-disable

Or

default ipv6 helper-mode disable
