7750 SR OS Router Configuration Guide Page 241
VRRP Owner Command Exclusions — By specifying the VRRP vrid as owner, The following
commands are no longer available:
• vrrp mismatch-discard — Owner virtual router instances do not accept VRRP advertisement
messages; IP address mismatches are not checked or logged.
• 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.
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.
Values 1 — 255
owner — Identifies this virtual router instance as owning the virtual router IP addresses. If the owner
keyword is not specified at the time of vrid creation, the vrrp backup commands must be
specified to define the virtual router IP addresses. The owner keyword is not required when
entering the vrid for editing purposes. Once created as owner
, a vrid on an IP interface cannot
have the owner parameter removed. The vrid must be deleted and than recreated without the
owner keyword to remove ownership.
