    摘要: A virtual router spans a number of physical routing devices. A set of physical ports on one of the physical routing devices is logically represented as a trunk. A respective port priority value is associated with each of those ports, and a device priority value is associated with the physical routing device. If a port in the trunk is out-of-service, then the device priority value can be adjusted by the port priority value associated with the out-of-service port. A corrective action can be implemented if the device priority value fails to satisfy a condition. For example, the physical routing device may failover to another one of the physical routing devices spanned by the virtual router.

    摘要: A virtual router spans a number of physical routing devices. One of the physical routing devices is designated as master, and the other physical routing devices are designated as backups to the master. A failover protocol that includes both a non-dampened state and a dampened state can be implemented. According to the failover protocol, an attempt to designate one of the backups as master in place of the current master is permitted while the virtual router is in the non-dampened state, while such an attempt is suppressed while the virtual router is in the dampened state.
