Important Considerations
Authentication passwords can be up to eight alphanumeric
characters.
Regarding primary routers, consider the following:
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 module or the
VRID of a neighboring VRRP router.
Regarding backup routers, consider the following:
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 module. You cannot
define a Primary and Backup VRRP router for the same virtual
router on the same routing device.
Regarding the address mode, consider the following:
In auto-learn mode, a module learns the IP addresses to
associate with the specified VRID.
In IP-address mode, the module 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.
