Hi
I have a problem concerning Stp.
Can a BPDU sent by a switch come back to it ?
I mean BPDU destination mac address is multicast, if a switch connected to
the BPDU sender has Multicast enabled, can the BPDU come back to the sender ?
Here is the schema:
switch A1 --------link one ---------------- switch B
| I
| |
switch A2 --------link two----------------------
STP is deactivated on switch B, but i strongly suspect switch A (which a cluster of 2 swittch A1 and A2) to send some BPDU
If switch B receive this BPDU, is there any chance that B forwards them back to switch A (link one and two are in a LACP) ?
I've got STP error on A due to this reception of STP frames and I don't think it is normal a switch send back a BDPU
it received on a link.
Thanks
Best regards.
