The Rapid Spanning Tree Library project contains a full implementation

of 802.1s as an library with API. There is two processes, using this

library: 'bridge' & 'mngr'. First simulates RSTP bridge behavior, second

is dedicated to link/unlink 'bridges' into virtual RSTP domain (VRSTPD).

Both 'bridge' & 'mngr' has its own simple CLI like language of commands;

these commands allow to manage the VRSTPD. There are tools to trace

state machine transitions and get traps about drastic changes.

Purpose: studying, debugging, development.

The library may be used in real bridges/routers while bounding to a real

system depending environment.

To run:

1. In one shell run 'mngr'

./mngr

You will get prompt of 'mngr'; type '?' and get full help of

'mngr' commands.

2. In another shell run bridge instance.

./bridge

You will get prompt of 'bridge'; type '?' and get full help

of bridge management commands.

3. You may (and should) run a number of bridge instances, each in its

separate shell (this way you will be able manage them).

For example, if there were two bridge instances, you may see examples

of the dialog in files mngr.txt, B5055.txt and B5056.txt.

Note: prompt both of 'mngr' and of 'bridge' instance contains time stamp,

while all these process run onto the same computer, these time stamps

are synchronized.
