Re: vlan types

Not sure in which context you are referring to these but -

you have 2 sites S1 & S2

1) Local vlan example. S1 and S2 are connected via a L3 routed link.

In S1 you have a vlan 10. And in S2 you have a vlan 10. But these are local vlans ie. a device in vlan 10 in S1 is not in the same vlan as a device in vlan 10 in S2 because S1 & s2 are separated by a routed link.

2) End-to-end vlan example. S1 & S2 are connected to via a L2 trunk link. S1 has a vlan 10 and S2 has a vlan 10 and vlan 10 is allowed on the trunk link.

This is an end-to-end vlan because a client in vlan 10 in S1 is now in the same vlan as a client in vlan 10 in S2 and the traffic can be L2 switched from one site to the other.

Re: vlan types

Local vlan would be a vlan that exists just on a particular switch.

end-to-end vlan would be a vlan that is propagated between switches via for example VTP (Vlan Trunking Protocol).
