Configuring all OSPFv3 interfaces as passive
OSPFv3 sends LSAs to all other routers in the same AS. To limit the flooding of LSAs throughout the AS, you can configure OSPFv3 to be passive.
Prerequisites
You must be in the OSPFv3 router configuration context, as indicated by the
switch(config-ospf6)#
prompt.
Procedure
Configure all OSPFv3 interfaces as passive using the following command. For command details, see
passive-interface default.
passive-interface default
switch(config-ospf6)# passive-interface default
