| The standby ip command allows you to configure primary and secondary HSRP addresses. | ||
Usage Guidelines |
| |||
|
| The standby ip command activates HSRP on the configured interface. If you specify an IP address, that | ||
|
| address is used as the designated address for the hot standby group. If you do not specifiy an IP address, | ||
|
| the designated address is learned through the standby function. So that HSRP can elect a designated |
router, at least one router on the cable must have been configured with, or have learned, the designated address. Configuring the designated address on the active router always overrides a designated address that is currently in use.
When you enable the standby ip command on an interface, the handling of proxy ARP requests is changed (unless proxy ARP was disabled). If the hot standby state of the interface is active, proxy ARP requests are answered using the MAC address of the hot standby group. If the interface is in a different state, proxy ARP responses are suppressed.
When you use group number 0, no group number is written to NVRAM, providing backward compatibility.
