I need some help doing some manual tweaking with MST(STP). Here is the scenario.
We have two load balancers with two uplinks (gigabit) going to two 6509s (one link each for a mesh configuration). There is a primary and a secondary load balancer.The second only takes over if the first box dies.
The load balancers can run MST but it has been recommended by the vendor not to run MST/STP so the load balancers are only doing passthru of BPDUs and NOT participating in the MST/STP algorithm. I need to know what the commands are to tweak the weighted values to make the load balancers fail in this particular order:
Primary LB - uplink #1 . then
Primary LB - upnlink #2 which goes to 6509#2, then
Secondary LB - uplink #1 which goes to 6509#1, then
Secondary LB - uplink #2 which goes to 6509#2.
Can someone give some advice please and perhaps the commands to make the Cisco weight out the links correctly so that MST/STP fails from link to link in the above listed order? Any information is highly appreciated.
Thank you,
