Packet routing in disaggregated scheduled fabrics

A device, comprising:

• a processor;
• a memory communicatively coupled to the processor;
• and
• a packet routing logic, configured to:
• establish a communication session with a network device;
• receive, from the network device, an update message associated with a host device;
• determine whether all of the network devices are selected by utilizing the list of the network devices to verify that each of the network devices has received an internal border gateway protocol (iBGP) update message;
• upon determining that all the network devices are selected, updating at least one routing or forwarding table based on the host route;
• extract reachability data from the update message;
• and
• determine, based on the reachability data, an encapsulation index indicative of a host route associated with the host device.

A method, comprising:

• identifying an interface associated with a host device;
• determining a host route based on the interface;
• assigning an encapsulation index based on the host route;
• generating reachability data based on the encapsulation index;
• determining an operational status of the interface;
• and
• generating an update message indicative of the encapsulation index and the operational status;
• utilizing a list of network devices to determine whether all of the network devices are selected;
• verifying that each of the network devices has received an internal border gateway protocol (iBGP) update message;
• and
• upon determining that all the network devices are selected, updating at least one routing or forwarding table based on the host route.
