Note: Our implementation does not validate the IP addresses in the advertisement packet or authenticate using an

authentication header.

Preemption Option (default, preempt)

The preemption option determines what the router does when it recovers from a failure, as follows:

¥ If the router is the master router for the IP address (it has priority 255), it always immediately preempts the

backup router and resumes its function in the network.The preemption option cannot change this.

¥ However, if the router is a backup router for the IP address and it determines that a router with a lower

priority is currently functioning as backup, the preemption option determines whether this router immediately

preempts the router with lower priority or waits for the lower priority router to go away before becoming the

active VRRP router.

The preemption option may differ among the backup routers for a VRID.

The preemption command is:eth vrrp set option <preempt | nopreempt> <vrid> [<port#>]

Listing and Deleting the VRRP Configuration

After you have configured a router for VRRP, you can list the VRRP records and the current VRRP status using

the command:

eth vrrp list [<port#>]

To delete the VRRP configuration in a router, you delete the attribute record and the extra logical interface using

these commands:

eth vrrp delete <vrid> [<port#>]

eth delete <port#>:<logical#>
