Abstract
First and second network devices may be configured to multihome a host. The first network device may advertise a first MAC and IP advertisement route indicative of a first link between the first network device and the host. The second network device may advertise a backup MAC and IP advertisement route indicative of a second link between the second network device and the host. Based on the backup MAC and IP advertisement route, the first network device may store a backup path for reaching the host via the second network device. After failure of the first link, the first network device may forward traffic destined for the host based on the stored backup path.
