HSRP Configuration Guidelines
Follow these guidelines when configuring HSRP:
• HSRP for IPv4 and HSRP for IPv6 are mutually exclusive. You cannot enable both at the same time.
• HSRPv2 and HSRPv1 are mutually exclusive. HSRPv2 is not interoperable with HSRPv1 on an
interface and the reverse.
• You can configure up to 32 instances of HSRP groups.
If you configure the same HSRP group number on multiple interfaces, the switch counts each
interface as one instance:
For example, if you configure HSRP group 0 on VLAN 1 and on Gigabit Ethernet 1/0/1, the switch
counts this as two instances.
