Configure Passive-Interface
Use the following command to suppress the interface’s participation on an OSPFv3 interface. This
command stops the router from sending updates on that interface.
To enable both receiving and sending routing updates, enter the
no passive-interface interface command.
When you configure a passive interface, the
show ipv6 ospf interface command adds the words
“passive interface” to indicate that hello packets are not transmitted on that interface.
