[c-nsp] MST spanning-tree

[David Hughes]

Hi

You'll need to pre-configure your vlan mappings.  This was discussed  
on this list only last week.  When we moved from RPVST to MST we went  
from odds-and-evens mapping to "blocks of 50 vlans" mapping.  It makes  
the config a whole lot smaller :)

All in all it's working well and when there are hundreds of vlans in  
use the traffic distribution over both paths is acceptable.


Thanks

David
