The no form of the command configures discarding all ICMP echo request messages destined to the
non-owner virtual router instance IP addresses.
Default no ping-reply — ICMP echo requests to the virtual router instance IP addresses are discarded.
shutdown
Syntax [ no ] shutdown
Context config>router>if>vrrp
config>router>if>ipv6>vrrp
Description This command administratively disables an entity. When disabled, an entity does not change, reset, or
remove any configuration settings or statistics.
The operational state of the entity is disabled as well as the operational state of any entities contained
within. Many objects must be shut down before they may be deleted.
The no form of this command administratively enables an entity.
Special Cases Non-Owner Virtual Router — Non-owner virtual router instances can be administratively
shutdown. This allows the termination of VRRP participation in the virtual router and stops all
routing and other access capabilities with regards to the virtual router IP addresses. Shutting down the
virtual router instance provides a mechanism to maintain the virtual routers without causing false
backup/master state changes.
If the shutdown command is executed, no VRRP advertisement messages are generated and all
received VRRP advertisement messages are silently discarded with no processing.
By default, virtual router instances are created in the no shutdown state.
Whenever the administrative state of a virtual router instance transitions, a log message is generated.
Whenever the operational state of a virtual router instance transitions, a log message is generated.
Owner Virtual Router — An owner virtual router context does not have a shutdown command.
To administratively disable an owner virtual router instance, use the shutdown command within the
parent IP interface node which administratively downs the IP interface.
ssh-reply
Syntax [ no ] ssh-reply
Context config>router>if>vrrp
Description This command enables the non-owner master to reply to SSH requests directed at the virtual router
instance IP addresses. This command is only applicable to IPv4.
Non-owner virtual router instances are limited by the VRRP specifications to responding to ARP
requests destined to the virtual router IP addresses and routing IP packets not addressed to the virtual
router IP addresses.
