I have a situation where the core swtich is sitting a site A and I need to need to extend a VLAN to site C, however the link between those two site is ran through site B where another procurve switch is sitting. If it is vlan 10 that I want to extend, on site B's switch can I just add vlan 10 and tag the two ports involved in the Site A>C link to pass VLAN 10 traffic. Site B does not need access to vlan 10. Any help is appreciated!
