Default HSRP Configuration
Table 32-1 shows the default HSRP configuration.
HSRP Configuration Guidelines and Limitations
Follow these guidelines when configuring HSRP:
• 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 30-11.
• All Layer 3 interfaces must have IP addresses assigned to them. See the “Configuring Layer 3
Interfaces” section on page 10-18.
