My concern is that if we have three switches connected in triangular fashion and flex link feature is used only on one switch then do we see any layer 2 issues?
For example if we consider this topology :
If all the links above are configured as trunk and all VLANS allowed then I wish to know -
- All ports on Switch B and C remain in fowarding state in STP?
- If switch B and C ports are in forwarding state in STP then will Switch B and C announce the MAC-ADDRESS table to Switch A over its directly connected interfaces?
- I understand that one interface on Switch A will remain in backup state and shall not SEND traffic but if it receives(I hope it can receive) the same MAC Address table on two interfaces(one being fwding in flex link and other being backup) then what would happen?
- Will there be MAC-FLAPS or Layer 2 loops observed?
