Method and apparatus for forwarding information base scaling

摘要

In one embodiment, a method includes receiving a packet at an edge device in a first network site in communication with a second network site through a transport network, the packet comprising a destination address for a host at the second network site, verifying at the edge device a connection with the host, and inserting the destination address in a forwarding information base at the edge device upon verifying the connection with the host. An apparatus and logic are also disclosed herein.

1. A method comprising:
receiving a packet at an edge device in a first network site in communication with a second network site through a transport network, the packet comprising a destination address for a host at the second network site, the edge device comprising a switch and the host comprising an endpoint in communication with a second edge device at the second network site; verifying at the edge device in the first network site, a connection with the host at the second network site, wherein verifying said connection comprises finding the destination address of the host in a database located at the edge device in the first network site; and inserting the destination address in a forwarding information base at the edge device upon verifying said connection with the host for use in forwarding packets belonging to a same flow as the packet received at the edge device; wherein the forwarding information base selectively downloads routes for active flows through verification of connection with hosts in remote network sites.
