HSRP Configuration Guidelines
Follow these guidelines when configuring HSRP:
• HSRP can be configured on a maximum of 32 VLAN or routing interfaces.
• In the procedures, the specified interface must be one of these Layer 3 interfaces:
– Routed port: a physical port configured as a Layer 3 port by entering the no switchport
interface configuration command.
– SVI: a VLAN interface created by using the interface vlan vlan_id global configuration
command and by default a Layer
3 interface.
– Etherchannel port channel in Layer 3 mode: a port-channel logical interface created by using
the interface port-channel port-channel-number global configuration command and binding
the Ethernet interface into the channel group. For more information, see the
“Configuring
Layer 3 EtherChannels” section on page 37-14.
• All Layer 3 interfaces must have IP addresses assigned to them. See the “Configuring Layer 3
Interfaces” section on page 11-24.
• HSRPv2 and HSRPv1 can be configured on the same switch if HSRPv2 is configured on different
interfaces than those on which HSRPv1 is configured.
• The version of an HSRP group can be changed from HSRPv2 to HSRPv1 only if the group number
is less than 256.
• If you change the HSRP version on an interface, each HSRP group resets because it now has a new
virtual MAC address.
