Configuring Vrrp Packet Attributes - HPE FlexNetwork HSR6800 series Configuration Manual

Configuring VRRP packet attributes

Configuration prerequisites
Before you configure the relevant attributes of VRRP packets, create a VRRP group and configure a
virtual IP address for it.
Configuration guidelines
•
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,
increase 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. This is 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.
•
After you specify an interface as the source interface for sending VRRP packets, this interface,
instead of the interface where the VRRP group resides, sends and receives VRRP packets. If
you specify the interface where the VRRP group resides as the source interface for sending
VRRP packets, the configuration does not take effect.
Configuration procedure
To configure VRRP packet attributes:
Step
1. Enter system view.
2. Enter the specified interface
view.
3. Configure the authentication
mode and authentication key
when the VRRP groups send
and receive VRRP packets.
4. Configure the time interval
for the master in the VRRP
group to send VRRP
advertisements.
5. Specify the source interface
for sending VRRP packets.
6. Disable TTL check on VRRP
packets.
