Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 interface interface-id Enter interface configuration mode, and enter the
Layer 3 interface on which you want to specify the

Step3 standby [group-number] ipv6 {link-local-address
| autoconfig}
Create (or enable) the HSRP for IPv6 group.
(Optional) group-number—The group number on the
interface for which HSRP is being enabled. The range is 0
to 4095. The default is 0. If there is only one HSRP group,
you do not need to enter a group number.
Enter the link-local address of the Hot Standby router
interface, or enable the link-local address to be generated
