Radia Perlman's spanning tree protocol gets an interactive tour
An interactive tour of the spanning tree protocol

Vincent Bernat's interactive guide to the spanning tree protocol lets you run a real RSTP implementation in your browser. Watch bridges elect a root, assign port roles, and recover from a cut link in under a second. It covers the protocol's history, Radia Perlman's famous poem, security concerns, and why RSTP still matters despite newer alternatives like BGP EVPN VXLAN.
I think that I shall never see a graph more lovely than a tree.

Also a good opportunity to read about https://en.wikipedia.org/wiki/Radia_Perlman in general (she is mentioned in the blog of course).

This blog is an unbelievable gold mine of information about networking, Linux, and other concepts. It's what I wish my own blog was in my head, if I could somehow summon the time and creativity.
