Parameters
Example
This command example specifies a new multicast address for VRRP.
Response
Command prompt.
eth vrrp set option
Specifies the preemption option in a VRRP attribute record for the VRID (virtual router
ID).
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.
To read more about VRRP Backup, see “ VRRP Backup” on page 6-16 of the
Technical Reference Guide.
The preemption setting may differ among the backup routers for a VRID.
NOTE:
This command takes effect immediately, but you must save the change if it is to
persist after you restart the interface or reboot the router.
<ipaddr>
a
a Dotted-decimal notation
IP address that is to be the new multicast address.
