Table 29-1 shows the default HSRP configuration.
HSRP Configuration Guidelines
Follow these guidelines when configuring HSRP:
• HSRP can be configured on a maximum of 32 VLAN or routing interfaces.
• In the following 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 27-12.
• All Layer 3 interfaces must have IP addresses assigned to them. See the “Configuring Layer 3
Interfaces” section on page 9-18.
