In BGP, the rule or set of rules the PortMaster follows for accepting, injecting, and/or advertising BGP routes to its BGP internal and external peers. You assign policies to a peer when you add it to the PortMaster during configuration. You can use the default policy easy-multihome, or create and assign your own policies. One policy can handle all three functions, or you can create separate policies for acceptance, injection, and advertisement. See also acceptance policy; advertisement policy; injection policy.
