Abstract

A method and system for best effort propagation of security group information is disclosed. The method includes determining if a reserved group identifier is associated with a destination and, if the reserved group identifier is associated with the destination, indicating that a packet received at a network node can be sent to another network node. The packet includes destination information that identifies the destination as a destination of the packet.

Claims

1. A method comprising:

determining if a reserved group identifier is associated with a destination; and

if said reserved group identifier is associated with said destination, indicating a packet received at a network node can be sent to another network node, wherein said packet comprises destination information that identifies said destination as a destination of said packet.
