I have labbed it on dynamips last night on 3725 routers with NM-16ESW
modules. All is working just fine. Doesn't matter if middle switch has
null domain name or specific domain name. Transparent VTP v2 forward all
unknown VTP advertisements between edge switches just fine, and v1 drops
everything. All behaves according documentation.
See if you can find another image which doesn't have this bug.
