I currently have a network which consists of one 2970G as a core switch and a number of 2950T and 2970G switches at the edge (see attachment 1.jpg).
What I would like to accomplish is redundancy in the core so if one switch fails traffic will automatically flow through the second core switch instead. (see attachment 2.jpg).
I don't know if this is possible to accomplish with 2 2970G, STP and redundant connections to the edge switches. Money has been set aside to invest in new core switches if needed.
Any tips, hints or recommendations is appreciated. Thank you.
