Establishing STP per VLAN basis instead of entire VLAN network, so one STP for one VLAN and this for the security purpose where cisco extended its feature further naimg as PVSTP+,remember both are pvstp and pvstp+ are cisco proprietary and doesn't find use in other switches
• Access link: An access link is a link that is part of only one VLAN, and normally access links are for end devices. Any device attached to an access link is unaware of a VLAN membership. An access-link connection can understand only standard Ethernet frames. Switches remove any VLAN information from the frame before it is sent to an access-link device.• Trunk link: A Trunk link can carry multiple VLAN traffic and normally a trunk link is used to connect switches to other switches or to routers. To identify the VLAN that a frame belongs to, Cisco switches support different identification techniques (VLAN Frame tagging). Our focus for CCNA examination is on Inter-Switch Link (ISL) and 802.1Q.A trunk link is not assigned to a specific VLAN. Many VLAN traffic can be transported between switches using a single physical trunk link.
Since VLAN's cannot communicate with other VLAN's directly, I believe you would have to set up a router to do that. I would check out how to set up a bridge between two VLAN's.
VLAN: How are packets distributed with respect to the different classifications?
The native VLAN is untagged. If the VLAN 99 traffic to the router is untagged (as it would be, because that is native on the switches), the router cannot interpret the data because there is no VLAN information in the header as expected. In turn, the router tags all VLAN 99 traffic outbound, and leaves VLAN 1 data untagged, so the switches are unable to correctly interpret either. VLAN traffic to the other VLANs should not be affected by the assignment of the native VLAN.
It is the VLAN that supports untagged traffic on an 802.1Q trunk

VLAN is a group of hosts with a common set of requirements that communicate as if they were attached to the same broadcast domain, regardless of their physical location. Inter VLAN is defined as two VLANS connected to each other and communicating.
A Port VLAN ID (pvid) is a default VLAN ID that is assigned to an access port to designate the virtual LAN segment to which this port is connected. The pvid places the port into the set of ports that are connected under the designated VLAN ID. Also, if a trunk port has not been configured with any VLAN memberships, the virtual switch's Port VLAN ID (pvid) becomes the default VLAN ID for the ports connection.
