Important Considerations
Authentication passwords can be up to eight alphanumeric
characters.
You can define one Primary router per VLAN.
Primary routers own the IP addresses that you associate with a virtual
router.
When you define a Primary virtual router, the possible VLANs that you
can select are the IP VLANs on the router that have no virtual routers
configured.
The virtual router ID (VRID) must be unique across all locally attached
LAN segments and unique for the local router.
When you define a Primary virtual router, you cannot use the VRID of
a virtual router that is already defined on the system or the VRID of a
neighboring VRRP router.
Backup routers back up the primary router of a specified virtual router
and assume Master state responsibilities for the virtual router should
the primary router fail.
When you define a Backup virtual router, you cannot use the VRID of a
primary router that is defined on the system. You cannot define a
Primary and Backup VRRP router for the same virtual router on the
same routing device.
In auto-learn mode, systems learn the IP addresses to associate
with the specified VRID.
In IP address mode, the system prompts you to select the interface
index from a list.
After a reboot, the address learning process restarts for each virtual
router in auto-learn address mode.
When you define a Primary virtual router, selecting auto-learn as
the address mode automatically adds all IP addresses that are
associated with the selected VLAN to the primary virtual router.
