How does a Bridging Loop occurs:

[img]http://www.cisco.com/image/gif/paws/10543/Image13.gif[/img]

Suppose Host A sends a frame to Host B. Both bridges receive the frame and correctly conclude that Host A is on Network 2. Unfortunately, after Host B receives two copies of the frame of Host A, both bridges again receive the frame on their Network 1 interfaces because all hosts receive all messages on broadcast LANs. In some cases, the bridges will then change their internal tables to indicate that Host A is on Network 1. If this is the case, when Host B replies to the frame of Host A, both bridges receive and subsequently drop the replies because their tables indicate that the destination (Host A) is on the same network segment as the source of the frame.

In addition to basic connectivity problems, such as the one described, the proliferation of broadcast messages on networks with loops represents a potentially serious network problem. In reference to Figure 20-1, assume that the initial frame of Host A is a broadcast. Both bridges forward the frames endlessly, use all available network bandwidth, and block the transmission of other packets on both segments.

A topology with loops such as that shown in Figure 20-1 can be useful, as well as potentially harmful. A loop implies the existence of multiple paths through the internetwork. A network with multiple paths from source to destination has what is called improved topological flexibility which increases overall network fault tolerance.

ok is there any chance by which we can modify default ports for an application
like ftp with port 2563
