Abstract
Techniques are disclosed for avoiding sending network traffic through a backup network device when an active network device is operational. An example device is configured to receive a first address resolution protocol (ARP) request from an active network device and a second ARP request from a backup network device. The device is also configured to, in response to receiving the first ARP request and the second ARP request, send a first ARP response to the active network device.
Claims18
A device comprising:
- one or more processors;
- memory coupled to the one or more processors, the memory storing instructions that upon execution cause one or more processors to:
- receive a first address resolution protocol (ARP) request from an active network device and a second ARP request from a backup network device;
- in response to receiving the first ARP request, send a first ARP response to the active network device;
- and
- in response to receiving the first ARP request and the second ARP request, refrain from sending a second ARP response to the backup network device.
A method comprising:
- receiving, by a device, a first address resolution protocol (ARP) request from an active network device and a second ARP request from a backup network device;
- in response to receiving the first ARP request, sending, by the device, a first ARP response to the active network device;
- and
- in response to receiving the first ARP request and the second ARP request, refraining, by the device, from sending a second ARP response to the backup network device.
A non-transitory computer-readable storage medium storing instructions, which, when executed, cause one or more processors of a device to:
- receive a first address resolution protocol (ARP) request from an active network device and a second ARP request from a backup network device;
- in response to receiving the first ARP request, send a first ARP response to the active network device;
- and
- in response to receiving the first ARP request and the second ARP request, refrain from sending a second ARP response to the backup network device.
