Methods and devices for distributing routes in a network are disclosed. The methods include identifying priority routes for a plurality of routes in a network device. The method also includes establishing communications with a neighboring network device and sending a first set of routes of the plurality routes to the neighboring network device. The first set of routes is selected based on a relative priority of the first set of routes to non-selected routes of the plurality of routes. The neighboring network device receives the first set of routes, and writes the first set of routes to forwarding hardware of the neighboring network device. The programmed routes are then used to route packets in the network.

Priority based route programing and advertising

Embodiments described herein relate to techniques for dynamically adjusting information propagation metrics for information propagation paths of network devices based on signal quality. Such techniques may include: obtaining a signal quality parameter for an interface of a network device; making a first determination, using the signal quality parameter, that a signal quality for an information propagation path using the interface is below a signal quality threshold; making a decision, by a signal quality analyzer and based on the first determination, to adjust an information propagation metric by an information propagation metric quantity; providing, by the signal quality analyzer, the information propagation metric quantity to an information propagation decision making device; and programming, by the information propagation decision making device, a new information propagation path that does not include the interface into a hardware component of the network device based on receiving the information propagation metric quantity.

Using signal quality parameters to adjust data propagation metrics

A first network device receives a message from a second network device with an indication that the first network device is to adjust a data rate of data being received by the first network device. The first network device includes a first buffer space that is greater than a second buffer space of the second network device. The first network device determines a set of computing devices connected to the second network device based on receiving the indication and defines a set of first data rates to use to send data to respective computing devices. The first network device adjusts a second data rate of received data to send the received data through the second network device to a computing device at a first data rate defined in the set of first data rates. The first network device uses the first buffer space to perform the adjusting.

Traffic shaping over multiple hops in a network

A non-transitory computer readable medium includes instructions, which, when executed by a processor, perform a method on a network device. The method includes receiving, from a configuration server, a master configuration script that includes an instruction set, a network topology for network devices, and a dictionary. The dictionary includes network device specific configuration scripts for the network devices. The method also includes executing the instruction set on the network device to configure the network device. Executing the instruction set includes obtaining link layer discovery protocol (LLDP) information for the network device, determining a most common interface (MCI) connected to the network device using the LLDP information, determining a network device identity using the MCI, obtaining, from the dictionary, a network device specific configuration script for the network device based on the network device identity, and executing the network device specific configuration script to configure the network device.

Method and system for auto-provisioning network devices in a data center using network device location in network topology

A method for configuring a switch. The method includes receiving a configuration request from a switch, where the configuration request includes switch neighbor information (SNI) for the switch and a Media Access Control (MAC) address for the switch, identifying a replacement entry including a second MAC address and the SNI. The method further includes, based on the identification obtaining configuration information associated with the replacement entry, where the configuration information specifies a configuration of a second switch associated with the second MAC address, generating a configuration script using the configuration information and sending the configuration script to the switch, where the configuration script is executed by the switch to configure the switch.

Method and system for zero touch replacement of network infrastructure

A system for routing packets that includes leaf network devices, spine network devices, and a border gateway protocol controller to perform a method for routing packets in a network. The method includes receiving packets at a leaf device and, using the destination IP address of the packet to determine to which spine network device the packet is to be sent. The spine network devices each include a non-overlapping portion of a routing table. The spine network devices include functionality to determine a route for the packet based on its destination IP address, to determine to which leaf network device the packet is to be sent, and to send the packet to the discovered leaf network device. The leaf network device that receives the packet includes functionality to, based on the destination MAC address of the packet, determine out of which leaf network device interface to send the packet.
