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.
Brouters are used as connecting devices in the networking
system, so it acts as a Bridge in a network & as a Router in
a internetwork
this is a hardware device that functions as both a bridge and a router to forward data from one network to another.
