Are there any problems or issues when both ISL and 802.1q trunks are used in
the same VTP domain?
For example, suppose the following:
----ISL trunk --------
Is the above a valid configuration? If so, do any special precautions need to
be taken related to STP or VTP because one trunk is ISL but the other one is
Example 2: Assume Sw1 is VTP server and sw2 and sw3 are VTP clients all in
the same VTP domain.
Sw1----ISL trunk--------Sw2-------802.1q trunk--------Sw3
Is this a valid configuration? Any gotcha's I need to be aware of?
I know that these aren't preferred configs but the Cisco lab is reputed to
test valid config's even if they're not good config's.
