I configured two mst regions in a conf where 2 Catalyst 6500 are the main bridge for instance 1 & 2. Lets say catalyst 1 is the bridge for mst1 & catalyst 2 is the bridge for mst2. these two switch are connected via an Etherchannel composed by two gigabit ethernel. The other switches are conected via fastEthernet interfaces once to catalyst1 and once to catalyst2.
The problem is that when whe send traffic (let's say we copy 5Gbytes of data). from one vlan belonging to an mst region all the switch show the same traffic in the concerned interface. Let's say the machine origen of the copy is in a vlan belonging to mst instance2 , all the switch will have traffic in the interface connected to catalyst 2.
Any ideas please??
