Hello,
I would like to know if i can mix RSTP ( other switch ) with RPVST with mutiple vlan. I seen on the network that i mix with the vlan 1 because the bpdu destination mac is similar to rpvst but with the other vlan i think that create a loop. I tested on a maquette : one Cisco root bridge with vlan 1,2 and 3 and 2 other swicths uses RSTP. when i create a loop between the three switchs . one port on the other switchs is alternate blocking and i don’t see a loop. I tagged all vlan exept the vlan 1 that is native.
What do you think of that?
