[c-nsp] Rapid and classic Spanning Tree Interoperation/Migration

[christian.macnevin at uk.bnpparibas.com]

Hi,

Has anyone got any good resources or just tips regarding upgrading a
       network to Rapid Spanning Tree?

I'm aware that it's backwards compatible, meaning that it 'negotiates down'
       to classic spanning tree, and the ports need to be reset manually to
       force it up to RSTP once all bridging members of the VLAN are
       talking the new protocol. So if you roll it out segment by segment,
       you still have a classic network, requiring quite a bit of work to
       force it into RSTP.



The other thing which concerns me is that it might be a bit of a big arse
       to take the network I'm looking at the whole way to RSTP, and I
       might only be able to do it on specific crucial segments. Is this
       even practical? Or does it effectively reduce the whole, once again,
       to a classic implementation?



Cheers

Christian
