The VRRP Operation Table contains the following fields:
IfIndex—Specifies the specific interface attached to the VRRP router.
VRID—Identifies the Virtual Router Identifier.
Oper State—Indicates the current router state. The possible field values are:
Master—–Indicates that the router functions as the forwarding router for the IP
♦
addresses associated with the virtual router. The Master router responds to ARP
requests, forwards packets with Virtual MAC Address (VMAC) as the destination
MAC, and accepts packets associated with the virtual IP addresses.
Initialize—Indicates that the router waits for a startup event. When the startup event
♦
is received, the router transits to the appropriate state.
Backup—Indicates that the router acts as backs up to the master router. The router
♦
continuously monitors if the Master router is available. The Master router is
monitored by the periodic advertisements the master sends or by specific messages
sent from the master announcing that it is going down.
Admin State—Indicates the router Administrative state.
Up—Indicates the router is currently up.
♦
Down—Indicates the router is currently down. The Admin State must be set to
♦
Down when defining VRRP Routers.
Priority—Indicates the router priority. The range is 0-255, where the default is 100.
The VRRP Priority value may determine if a higher priority VRRP router overrides a
lower priority VRRP router. The VRRP router that owns the IP address associated with
the virtual router MUST have priority of 255.
Master IP Address—Indicates the main virtual IP address. If the Master IP address
becomes unavailable, a dynamic IP address takes over.
Primary IP Address—Identifies the virtual IP address associated with the (virtual
router) VRRP router that becomes the Master router, should the current (virtual router)
Master router fail. The field default is 0.0.0.0. If the default primary IP address is
selected as 0.0.0.0, the lowest numeric IP address is used.
Authentication—Indicates the authentication type that occurs when VRRP protocols
are exchanged. The possible field values are:
None—Specifies that no authentication process takes place.
♦
Password—Specifies that passwords are used to authenticate VRRP protocol
♦
exchanges.
