what is difference between local vlan & end-to-end vlan.
Thanks in advance
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.
