Configuring VRRP packet attributes
Configuration prerequisites
Before you configure the relevant attributes of VRRP packets, create a VRRP group and configure a virtual
IPv6 address.
Configuration procedure
Follow these steps to configure VRRP packet attributes:
To do… Use the command… Remarks
Enter system view system-view —
Enter the specified interface view
interface interface-type
interface-number
—
Configure the authentication mode
and authentication key when the
VRRP groups send or receive VRRP
packets
vrrp ipv6 vrid virtual-router-id
authentication-mode simple key
Optional
Authentication is not performed by
default.
Configure the time interval for the
master in the VRRP group to send
VRRP advertisement
vrrp ipv6 vrid virtual-router-id timer
advertise adver-interval Optional
100 centiseconds by default
NOTE:
•
You might configure different authentication modes and authentication keys for the VRRP groups on an
interface. However, the members of the same VRRP group must use the same authentication mode and
authentication key.
• Excessive traffic might cause a backup to trigger a change of its status because the backup does not
receive any VRRP advertisements for a specified period of time. To solve this problem, prolong the time
interval to send VRRP advertisements.
• Configuring different intervals for sending VRRP advertisements on the routers in a VRRP group might
cause a backup to trigger a change of its status because the backup does not receive any VRRP
advertisements for a specified period of time. To solve this problem, configure the same interval for
sending VRRP advertisements on each router in the VRRP group.
Displaying and maintaining VRRP for IPv6
