Abstract
A routing device and a further routing device of a switched network form a virtual router and are addressable by a virtual Media Access Control (MAC) address. The further routing device receives at least one data frame and sends, to the routing device, a request instructing the routing device to send an alert message for conveying information about the virtual MAC address throughout the switched network.
Claims18
A method of managing data frames, performed by a further routing device of a switched network, the method comprising:
- receiving at least one data frame;
- and
- sending, to a routing device, a request instructing the routing device to send an alert message for conveying information about a virtual MAC address throughout the switched network, wherein the routing device and further routing device form a virtual router and are addressable by the virtual MAC address;
- wherein the virtual MAC address is a Virtual Router Redundancy Protocol (VRRP) Media Access Control address, a VRRP Extended MAC address, or a Hot Standby Router Protocol MAC Address.
A further routing device of a switched network, the further routing device comprising:
- processing circuitry;
- memory containing instructions executable by the processing circuitry to configure the further routing device to:
- receive at least one data frame;
- and
- send, to a routing device, a request instructing the routing device to send an alert message for conveying information about a virtual MAC address throughout the switched network, wherein the routing device and further routing device form a virtual router and are addressable by the virtual MAC address;
- wherein the virtual MAC address is a Virtual Router Redundancy Protocol (VRRP) Media Access Control address, a VRRP Extended MAC address, or a Hot Standby Router Protocol MAC Address.
A non-transitory computer readable medium storing a computer program product for managing data frames, the computer program product comprising software instructions which, when run on processing circuitry of a further routing device of a switched network, causes the further routing device to:
- receive at least one data frame;
- and
- send, to a routing device, a request instructing the routing device to send an alert message for conveying information about a virtual MAC address through the switched network, wherein the routing device and further routing device form a virtual router and are addressable by the virtual MAC address;
- wherein the virtual MAC address is a Virtual Router Redundancy Protocol (VRRP) Media Access Control address, a VRRP Extended MAC address, or a Hot Standby Router Protocol MAC Address.
A method of managing data frames, performed by a further routing device of a switched network, the method comprising:
- receiving at least one data frame;
- and
- sending, to a routing device, a request instructing the routing device to send an alert message for conveying information about a virtual MAC address throughout the switched network:
- only when the receiving of the at least one data frame comprises detecting at least one data frame comprising a destination address field including the virtual MAC address;
- and
- less than a specific number of times counted from detection of flooding;
- wherein the routing device and further routing device form a virtual router and are addressable by the virtual MAC address.
A further routing device of a switched network, the further routing device comprising:
- processing circuitry;
- memory containing instructions executable by the processing circuitry to configure the further routing device to:
- receive at least one data frame;
- and
- send, to a routing device, a request instructing the routing device to send an alert message for conveying information about a virtual MAC address throughout the switched network:
- only when the received at least one data frame comprises a destination address field including the virtual MAC address;
- and
- less than a specific number of times counted from when the at least one data frame was received;
- wherein the routing device and further routing device form a virtual router and are addressable by the virtual MAC address.
A non-transitory computer readable medium storing a computer program product for managing data frames, the computer program product comprising software instructions which, when run on processing circuitry of a further routing device of a switched network, causes the further routing device to:
- receive at least one data frame;
- and
- send, to a routing device, a request instructing the routing device to send an alert message for conveying information about a virtual MAC address through the switched network only when the received at least one data frame comprises a destination address field including the virtual MAC address:
- only when the received at least one data frame comprises a destination address field including the virtual MAC address;
- and
- less than a specific number of times counted from when the at least one data frame was received;
- wherein the routing device and further routing device form a virtual router and are addressable by the virtual MAC address.
