DES-7200 Configuration Guide Chapter 1 VRRP Configuration
1-10
Note
In case the advertisement sending interval in VRRP advertisement
received by VRRP backup router is inconsistent with the
advertisement interval set locally, if the timer learning function is not
configured on the VRRP backup router, the VRRP backup router will
drop the VRRP advertisement; otherwise, it will receive the VRRP
advertisement and calculate failure judgment interval of VRRP Master
router by the advertisement interval.
1.3.11 Setting the Description
String of the Router in the
VRRP Backup Group
This command will set the descriptor for the VRRP group to facilitate identifying the
VRRP group.
Command Purpose
DES-7200(config-if)# vrrp group description
text
Set the description string of the VRRP
group.
DES-7200(config-if)# no vrrp group
description
Cancel the description string of the VRRP
group.
By default, the VRRP backup group has no description string configured. The length of
the VRRP backup group description string is 80 by maximum.
Note
If blanks are contained in the description string of the VRRP backup
group, quotation marks (") must be used to identify the description
string.
1.3.12 Setting the Delay Reload of
the VRRP Backup Group
This command will set the delay reload time of the VRRP backup group on an interface.
The delay reload time has two types: the one when the system reloads and the one
when the interface becomes active. You can set those two types of delay reload time
separately or simultaneously.
In the non-preemption mode, when the VRRP backup group with higher priority
reloads, it can not preempt the master router in the same backup group. However,
even though the non-preemption mode is configured, the reloading VRRP backup
group can also preempt the VRRP master router. That is because when the router
reloads or the interface becomes active, the VRRP backup group on the interface fails
to receive the VRRP packets sent from the master router in the same backup group in
time.
