Unanswered Question

Just for closing this conversation.

Hello you all.

Well this is the MSTP configuration I think could work. The network schema is in the attachment.

& one more question witch software to use for simulating a catalyst 6500 or another MSTP capable switch?

Thanks

Now the config(according to my schema):

DS1 (catalyst 6500)

interface Fasethernet 7/2

switchport mode trunk

switchport encapsulation dot1Q

switch trunk allowed vlan 1,2,3

switchport nonegociate

interface Fasethernet 7/3

switchport mode trunk

switchport encapsulation dot1Q

switch trunk allowed vlan 2,4,5

switchport nonegociate

interface Fasethernet 7/4

switchport mode trunk

switchport encapsulation dot1Q

switch trunk allowed vlan 4,5,6

switchport nonegociate

spanning-tree mode mst

spanning-tree extend system-id

.

spanning-tree mst configuration

name procurve-cisco

revision 1

instance 1 vlan 1, 3, 5

instance 2 vlan 2, 4, 6

spanning-tree mst 0-1 priority 0

spanning-tree mst 2 priority 4096

DS2(catalyst 6500)

interface Fasethernet 7/2

switchport mode trunk

switchport encapsulation dot1Q

switch trunk allowed vlan 1,2,3

switchport nonegociate

interface Fasethernet 7/3

switchport mode trunk

switchport encapsulation dot1Q

switch trunk allowed vlan 2,4,5

switchport nonegociate

interface Fasethernet 7/4

Thanks for any comments.

Hello Osvaldo,

the configuration looks like fine.

About MSTP emulation there are packages for instruments like Agilent router tester or IXIA but they work on dedicated hardware.

I don't know if under linux or freebsd you can find something useful.

Hope to help

Giuseppe
