Default HSRP Configuration
Table 36-1 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 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 34-14.
