All other virtual router instances participating in this message domain must have the same vrid
configured and cannot be configured as owner. Once created, the owner keyword is optional when
entering the vrid for configuration purposes.
A vrid is internally associated with the IP interface. This allows the vrid to be used on multiple IP
interfaces while representing different virtual router instances.
For IPv4, up to four vrrp vrid nodes can be configured on a router interface. Each virtual router
instance can manage up to 16 backup IP addresses. For IPv6, only one virtual router ID can be
configured on a router interface.
The no form of the command removes the specified vrid from the IP interface. This terminates VRRP
participation and deletes all references to the vrid in conjunction with the IP interface. The vrid does
not need to be shutdown to remove the virtual router instance.
Special Cases Virtual Router Instance Owner IP Address Conditions — It is possible for the virtual router
instance owner to be created prior to assigning the parent IP interface primary or secondary IP
addresses. When this is the case, the virtual router instance is not associated with an IP address. The
operational state of the virtual router instance is down.
VRRP Owner Command Exclusions — By specifying the VRRP vrid as owner, The following
commands are no longer available:
Default no vrrp — No VRRP virtual router instance is associated with the IP interface.
Parameters vrid — The virtual router ID for the IP interface expressed as a decimal integer.
owner — Identifies this virtual router instance as owning the virtual router IP addresses. If the owner

• vrrp priority — The virtual router instance owner is hard-coded with a priority value of 255
and cannot be changed.
• vrrp master-int-inherit — Owner virtual router instances do not accept VRRP advertisement
messages; the advertisement interval field is not evaluated and cannot be inherited.
• ping-reply, telnet-reply and ssh-reply — The owner virtual router instance always allows Ping,
Telnet and SSH if the management and security parameters are configured to accept them on the
parent IP interface.
• vrrp shutdown — The owner virtual router instance cannot be shutdown in the vrrp node. If
this was allowed, VRRP messages would not be sent, but the parent IP interface address would
continue to respond to ARPs and forward IP packets. Another virtual router instance may detect
the missing master due to the termination of VRRP advertisement messages and become master.
This would cause two routers responding to ARP requests for the same IP addresses. To shut-
down the owner virtual router instance, use the shutdown command in the parent IP interface
context. This will prevent VRRP participation, IP ARP reply and IP forwarding. To continue par-
ent IP interface ARP reply and forwarding without VRRP participation, remove the vrrp vrid
instance.
