Modifies an existing virtual router configuration on a Multilayer Switching
Module.

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, the 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.
