MSTP 2 VLan multiple uplink config
UPDATE
Figured following out.
When I execute sh spanning-tree it figures out that Trk1 is in "forwarding" state on both switches. Trk2 is in "forwarding" state on switch B and in "blocking" state on switch A. Nevertheless Trk2 seems to forware because I can ping between the switches.
Why is that possible when on one switch the state is "blocking"?
Hi,
I have two HP switch with the configuration attached. There are 2 static VLans on each switch (default, cluster). Trk1 connects the Cluster VLan of the switches and Trk2 connects the default VLan between the switches. Trk3 on each switch connects to a third switch which contains the production Lan.
What I want to configure is that the uplinks Trk1 and Trk2 are forwarding simultaneously. Trk3 should be active either on Switch A or Switch B. The problem is, that I can't get Trk1 and Trk2 forwarding at the same time. Trk1 is forwarding and Trk2 always blocking.
Hope somebody can help.
Thank's in advance

Re: MSTP 2 VLan multiple uplink config
Quick question: how is the third switch configured? I haven't had more than a glance at the configuration but it will make a lot of difference.

Re: MSTP 2 VLan multiple uplink config
Hi!
The third switch is a Netgear. I don't have access to that but the customer gave me the information that spanning tree is enabled on it with default configuration.

Re: MSTP 2 VLan multiple uplink config
I would get rid of:
"spanning-tree Trk1 admin-edge-port", because it isn't an edge port.
Otherwise, your configuration looks fairly good to me. You just seem to have a slight misunderstanding of what is happening. You can't get Trk1 and Trk2 forwarding - in the same instance.
However, you already have multiple spanning trees configured. I think your configuration will work as it is.
You just need to do:
'show span instance 1' and
'show span instance 2'
to confirm that the correct trunks are blocked.
