SmartSwitch Router User Reference Manual 203
Chapter 14: VRRP Configuration Guide
Note: Since 100 is the default priority, line 9, which sets the priority to 100, is actually
unnecessary. It is included for illustration purposes only.
Configuration of Router R3
The following is the configuration file for Router R3 in Figure 19.
Lines 8 and 9 set the backup priority for Router R3 at 100 for virtual routers
VRID=1
and
VRID=2
. Since Router R1 has a priority of 200 for backing up virtual router
VRID=2
, and
Router R2 has a priority of 200 for backing up virtual router
VRID=1
, Router R3 is the
secondary Backup for both virtual routers
VRID=1
and
VRID=2
.
The following table shows the priorities for each virtual router configured on Router R3.
Note: Since 100 is the default priority, lines 8 and 9, which set the priority to 100, are
actually unnecessary. They are included for illustration purposes only.
