router. If the packet to be processed is an IP packet, it will be routed through IP.
Certainly, if IP cannot find a route, it will discard the packet instead of forwarding
it to the bridge for processing. If the packet uses a protocol other than IP (for
example, if it is the packet from the network like AppleTalk or DecNet), it will be
bridged.

When there are multiple parallel links between two bridge devices, and the
corresponding link ports are all added to the bridge set, the spanning tree protocol
can be used to avoid bridge loop, and can ensure that only one link is available to
transmit data. Other corresponding link ports are all in congestion state. This can
guarantee normal bridging between two bridged devices at the cost of wasting
link bandwidth. The link set can not only guarantee the bridging function but save
the link bandwidth as well. The solution is to add multiple parallel links to a link
set. Each corresponding link port can still independently take part in the spanning
tree calculation, which guarantees the bridging function. During data forwarding,
each link in the link set can share loads, thus utilizing all link bandwidths.
