Network routing

摘要

An example of network routing comprising a host route injection that can include injecting a host route and a next hop of the host route into a routing table. The host route can be injected into a top of rack network device and transferred to an Aggregation network device routing table. The routing entry can be updated by sharing routing updates from the compute host through the top of rack network device.

1. A system for network routing comprising:
an Aggregation (AGG) network device comprising:
a routing table that stores Address Resolution Protocol (ARP) entries including corresponding next hop Internet Protocol (IP) addresses; andan ARP table that caches only a next hop MAC address of a host route; a top of rack (TOR) network device that peers with the AGG network device as a first route reflector client; and a compute host that peers with the TOR network device as a second route reflector client and injects the next hop MAC address of the host route into the TOR through network peering, wherein the AGG network device, the TOR network device, and the compute host share a common local area network.
