Setting all OSPFv3 interfaces to the passive state

1. Enter the configure terminal command to access global configuration mode.
   

   device# configure terminal

2. Enter the ipv6 router ospf command to enter OSPFv3 router configuration mode and enable OSPFv3 globally.
   

   device(config)# ipv6 router ospf

3. Enter the default-passive-interface command to mark all interfaces passive by default.
   

   device(config-ipv6-router-ospf-vrf-default-vrf)# default-passive-interface

Example

The following example sets all OSPFv3 interfaces as passive, causing them to drop all the OSPFv3 control packets.

device# configure terminal
device(config)# ipv6 router ospf 
device(config-ipv6-router-ospf-vrf-default-vrf)# default-passive-interface
