There is provided a method for use by a first processing unit in or to be installed in a router. The first processing unit is configured or responsible for routing (or forwarding) packets to and from other routers. There may be other such first processing units in or installed in the router. In a first step (S1), information is received at the first processing unit which requires dissemination to other routers. The information also requires processing to determine what, if any, reconfiguration of the routing (forwarding) performed by the first processing unit is required. In a second step (S2b) the information is forwarded in a packet to other routers as required according to the routing (forwarding) configuration for the first processing unit. In a third step (S2c) the information is forwarded to at least one other first processing unit in the router (if there are any other first processing units in the router) not already in receipt of the information. If an expedited dissemination procedure is required, the second and third steps (S2b, S2c) are performed before the processing (to determine what if any reconfiguration is required) has been performed (completed) and/or before the first processing unit has been informed of the result of such processing and/or before any reconfiguration required in the first processing unit has been requested, arranged or performed (completed). |
