Hi guys,
Is it possible for a Cat to relearn the vlan's via vtp after the vlan.dat
file is deleted? I ask because I thought that before vtp can propagate vlan
info, both switches have to share the same vtp domain name and if the
vlan.dat file has been deleted, then wouldn't the vtp domain name also be
deleted? Isn't that the way it works?
