A non-transitory computer readable medium that includes instructions which, when executed by one or more hardware processors, causes performance of operations. The operations include receiving, at a first network device in a first network, a multicast message comprising data to be transmitted at least to two or more client devices that have roamed from the first network to a same second network, determining that at least one client device has roamed from the first network to the second network, and responsive at least to the determining operation, forwarding, by the first network device to a second network device in the second network, a single copy of the data for distribution to each of the two or more client devices.

Method and system for roamed client device handling

The present disclosure relates to a network device that indicates a master network controller in a virtual redundant router protocol (VRRP) peer. In example implementations, the network device determines a bake-off time and refrains from sending packets during the bake-off time to a network. Also, the network device determines whether a first packet is received from the network. If either the bake-off time expires or the first packet is received from the network, the network device determines whether a spanning tree protocol (STP) convergence has completed. If so, the network device starts a VRRP state machine. If both the STP convergence has completed and the VRRP state machine has been started, the network device transmits a broadcast message indicating that the network device acts as a master network controller in the network.

Indicating a master network controller in a virtual router redundancy protocol

The present disclosure discloses a method and a network device for controlling DHCP pool exhaustion in dynamic network environments. Specifically, a network device determines that a client device is assigned an Internet Protocol (IP) address by a DHCP server. The network device detects that the client device is disconnected from a network associated with the IP address, for example, by receiving a de-association message from the client device; determining that a session or an entry corresponding to the client device has timed out; determining that the client device has failed to respond to one or more messages transmitted to the client device; determining that the client device has connected to another network different than said network; etc. In response, the network device then generates a DHCP release message on behalf of the client device, and transmits the DHCP release message to the DHCP server.

Method to control dynamic host configuration protocol pool exhaustion in dynamic network environments

The present disclosure discloses a method and network device for adaptive DHCP assignment with VLAN pool. Specifically, a network device can assign a client device to a first Virtual Local Area Network (VLAN). The network device then detects a first DHCP Discover message, transmitted by a client device, corresponding to a first VLAN. Also, the network device determines that no DHCP offer message, responsive to the first DHCP Discover message, is transmitted to the client device. Then, the network device transmits on behalf of the client device a second DHCP Discover message for the second VLAN to a DHCP server, and receives a DHCP Offer message in response to the second DHCP Discover message. The network device then assigns the client device to a second VLAN, and subsequently transmits the DHCP Offer message for the second VLAN to the client device.

Adaptive dynamic host configuration protocol assignment with virtual local area network pool

In general, in one aspect, embodiments relate to a non-transitory computer readable medium comprising instructions that, when executed by a processor, perform a method. The method includes receiving, by a controller, a first plurality of multicast advertisement packets from a first networking device on an external network, wherein the plurality of multicast advertisement packets are received at a first frequency, storing, by the controller, one of the first plurality of multicast advertisement packets in an advertisement packet repository, and transmitting, by the controller, information in the one of the plurality of advertisement packets on an internal network at a second frequency, wherein the second frequency is less frequent than the first frequency.
