brouter

A Bridge Router or brouter is a network device that works as a bridge and as a router. The brouter routes packets for known protocols and simply forwards all other packets as a bridge would. Brouters operate at both the network layer for routable protocols and at the data link layer for non-routable protocols. As networks continue to become more complex, a mix of routable and non-routable protocols has led to the need for the combined features of bridges and routers. Brouters handle both routable and non-routable features by acting as routers for routable protocols and bridges for non-routable protocols. Bridged protocols might propagate throughout the network, but techniques such as filtering and learning might be used to reduce potential congestion.

v. feed, graze, browse; chatter, nibble

A combined bridge and router that operates without protocol restrictions, routes data using a protocol it supports, and bridges data it cannot route.

A device which bridges some packets (i.e. forwards based on data link layer information) and routes other packets (i.e. forwards based on network layer information). The bridge/route decision is based on configuration information.
