ipv6 ospf passive
Congures an interface as a passive interface and suppresses both receiving and sending routing updates to the passive interface.
Syntax
ipv6 ospf passive
Parameters None
Default Not congured
Command Mode INTERFACE
Usage Information You must congure the interface before setting the interface to passive mode. The no version of the this
command disables Passive interface conguration.
NOTE: As loopback interfaces are implicitly passive, the conguration to suppress sending and receiving
of OSPF routing updates does not take eect on the loopback interfaces. However, network information
corresponding to these loopback interfaces is still announced in OSPF LSAs that are sent through other
interfaces congured for OSPF.
Example
OS10(config)# interface ethernet 1/1/6
OS10(conf-if-eth1/1/6)# ipv6 ospf passive
Supported Releases 10.3.0E or later
ipv6 ospf priority
Sets the priority of the interface to determine the DR for the OSPFv3 network.
Syntax
ipv6 ospf priority number
Parameters number — Enter a router priority number, from 0 to 255.
Default 1
Command Mode INTERFACE
Usage Information When two routers attached to a network attempt to become the DR, the one with the higher router priority takes
precedence. The no version of this command resets the value to the default.
Example
OS10(config)# interface ethernet 1/1/6
OS10(conf-if-eth1/1/6)# ipv6 ospf priority 4
Supported Releases 10.3.0E or later
log-adjacency-changes
Enables logging of syslog messages about changes in the OSPFv3 adjacency state.
Syntax
log-adjacency-changes
Parameters None
Default Disabled
Command Mode ROUTER-OSPFv3
Usage Information The no version of this command resets the value to the default.
Example
OS10(config)# router ospfv3 100
OS10(config-router-ospfv3-100)# log-adjacency-changes
