[j-nsp] interoperation between MSTP and old STP

[Victor Sudakov]

Colleagues,

I have several EX4200 switches with redundant links, all are running
MSTP with a couple of MSTIs.

If I include an older switch which can only run old-fashioned STP,
will they interoperate and still keep the topology loop-free? What if
it can run STP and RSTP, but not MSTP?

A link to some good documentation is also appreciated.

TIA for any input.
