The common types of trunking are; VLAN trunking, LTR trunking systems, EDACS trunking systems, Motorola trunking tystems.
VLAN
What is the purpose of VLAN trunking
vlan trunking protocols. eg :802.1q ,ISL
Trunking
The frames are assigned to the native VLAN.
One sub-interface per VLANA compatible trunking protocol encapsulation for each sub-interfaceOne IP network or sub-network for each sub-interface
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.
The answer is 'Trunking'. The definition of trunking is = The aggregation of multiple logical connections on one physical connection between connectivity devices. In the case of VLANS, trunking allows data from multiple VLANS to share interface on a switch. Network + Guide To Networks Review Question Chapter 6 #18
native vlan
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.
VLAN's, or virutal local area networks, appear at the application level or Level 7 o the OSI model. VLAN's use tagging or pot+tagging to route traffic to and from a specific area (like a specific departement in a business). VLAN technology relies on ethernet connectivity throughout the network it functions on (a more ubiquitious medium than standard trunking and TCIP, etc). VLAN's require an edge switch to tag the outgoing traffic and recieve the incomming traffic and allows you to prioritize traffic (tagged v/s untagged) so you can provide services like ip telephony, video sessions, SIP, etc.
