Folks,
Here is complete results of my experiments. Hope this benefits you.
SW1-------SW4--------SW2
X,Y,Z = Domain,Mode,Ver
Mode 'Any' = client or server or transparent
*Case-1)*
cisco,Server,2 -------- cisco,Any,2 --------- cisco,Client,2
*Result:*
Any vlan changes on SW1 is propogated to SW4 and SW2
Note that when both SW1 and SW4 are VTP servers, changes
on one server is updated by other server. Also, SW4 does't
update Vlan changes while in Transparent mode.
*Case-2)*
cisco,Server,2 -------- iewb,Any,2 ---------- cisco,Client,2
*Result:*
Any vlan changes on SW1 is NOT propogated to SW4 and SW2
*Case-3)*
cisco,Server,1 -------- cisco,Any,1 --------- cisco,Client,1
*Result:*
Any vlan changes on SW1 is propogated to SW4 and SW2
Note that when both SW1 and SW4 are VTP servers, changes
on one server is updated by other server. Also, SW4 does't
update Vlan changes while in Transparent mode.
*Case-4)*
cisco,Server,2 -------- iewb,Any,2 ---------- cisco,Client,2
*Result:*
Any vlan changes on SW1 is NOT propogated to SW4 and SW2
What bothers me is that how to get VTP updates from SW1 to SW2 ?
My task doesn't allow me to do Q-in-Q or L2protocol tunnelling.
All ideas are welcome.
Naveen.
