[c-nsp] VTP Pruning point .

[Ibrahim Abo Zaid]

Dears

i have a question about VTP Pruning which is used to optimize broadcast
forwarding over trunk links in switched networks

i think before doing so the switches needs to synchronizes VLAN
configurations between each other so i think VTP update
messages shall contain ACTIVE VLANs (VLANs which have active ports @ the
switch) instead of ALL-DEFINED VLANs

and that truns Trunks from ALL-VLANs members state to ACTIVE-VLAN state
means it would be members of Active VLANs only not All domain VLANs

i couldn't find any article verifies that point so if any one has an idea is
that true or something else is used i will be appreciated for any help :)

best regards
