What is the realtionship between Learning Domains and Logical Bridge
Domains?
In what instance would you not want a 1-to-1 mapping between LDs and
LBDs?

...as the release notes say, a Logical Bridge Domain is specified
as a list of Learning Domains. This is the relationship between them.
...and also as the release notes say, typically a Logical Bridge
Domain would consist of a single Learning Domain.
I take it that the release notes are not entirely clear.
A Learning Domain defines which ports share an address space. It
does not directly affect which ports are allowed to intercommunicate.
A Logical Bridge domain is used to divide a GIGAswitch/FDDI system
into totally separate networks, which naturally have different spanning
trees.
One might use multiple learning domains in a topology where MAC
addresses are duplicated because of multiple interfaces and DECnet.
See note 741.* for the earlier discussion on this topic.

Thanks. The release notes were not very clear.
