MST interaction

pentagel · ‎07-06-2007

Hello,

I have some questions about MST interaction.

Can MST interact with all STP? Or more precisely, can MST Interact with PVST, PVST+, RSTP and RPVST?

Also, what would happen if you take a triangle type of topology and have MST, RSTP and CST? Could MST interact with both?

Thanks.

Yes, MST can interact with other STP standards. MST is a IEEE standard, so it has to interact with other STPs.

MST interacts with other STPs through IST instance. At the MST region boundary, other STPs doesn't know that their neighbor is running MST.

Refer to below document on how MST functions:
