The whole point of VTP is to communicate VLAN information across multiple
switches to allow easy configuration. I don't think you can block the
advertisement of the existence of VLANs, but by setting your trunk to
support only certain VLANs, you block the otehr VLAN traffic from transiting
the trunk.
VTP Pruning is a v2 feature that stops traffic from being sent unnecessarily
across a trunk to a switch that has no ports that belong to the VLAN

Subject: ISL Trunking between 6500 & 2924
Hi All
I've set up ISL between a 6500 & a 2924XL, I only wish to advertise VLANS
1-50 to the 2924 but have 1-60 set up on the 6500, the 6500 is server & the
2924 is client in the same domain - problem is the 2924 always picks up all
the VLANS set up on the 6500 !
CONFIG ON 6500
clear trunk 4/5 51-1005,1025-4094
set trunk 4/5 on isl 1-50
Anyone aware of any issues as the config should be correct ?
Thanks - Martin
