Defining VRRP Attributes
Each time you define a VRID in a router, you must define an attribute record for it in
that router. The following sections describe how to define the record and set the
attributes.
NOTE:
The VRRP attribute commands do not require a restart or reboot to take effect.
However, you do need to save your changes if they are to persist after a restart or
reboot.
Adding a VRID Attribute Record
To define a record to contain the attributes for a VRID in a router, use this command:
-> eth vrrp add <vrid> [<port#>]
The port number is needed only if the router is an Ethernet hub router with two ports
(port 0 and port 1).
To see the VRID attribute records currently defined, use the eth vrrp list command, as
follows:
-> eth vrrp list
Priority Attribute (0-255, default, 100)
The priority value determines which backup router takes over when a router fails. The
master router must be assigned the highest priority (255). Lower priorities are
assigned to its backup routers, that is, the other routers in which the same VRID is
defined.
For example, suppose routers A, B, and C all have VRID 7 defined. If router B should
take over if router A fails and if router C should take over if both A and B fail, you
would assign priority 255 to A and lower priorities to B and C, such as, priority 100 to
B and priority 50 to C.
The priority command is:
-> eth vrrp set priority <priority> <vrid> [<port#>]
