Re: redundent link
What your looking for seems to be port-trunking, either configure manually or use LACP.
From STP point of view, a port-trunk behaves as a single link, both ports are active.

SolutionIn this case just make sure that the 8206 is the root switch for the MSTP.
One more thing if you are not really going to use the MSTP instances is to change it to RSTP using the command
#spanning-tree force-version RSTP-operation
Then assing the 8206 switch as root by assinging priority of 0
#spanning-tree priority 0
dont forget to save the config.
#write memory.

Re: redundent link
Assuming you have 2610-24 switches and are linking them with gigabit using port 25 then you would run the following command at the CLI of the switch. You need to run this on both 2610 switches. If you are using a different port then change the "25" in the command.
conf (to enter configuration mode)
spanning-tree 25 path-cost 50000
wr mem (to commit the change to flash)
The default cost for a 1Gb link is 20000. By increasing the cost of the link between the 2 switches, spanning tree should default to using the gigabit fibre links back to the 8206zl switch instead.
Also a good idea to set the 8206zl as the root of the spanning tree using the "spanning-tree priority 1" command.
Grab a copy of the "Advanced Traffic Management Guide" for your switches to get further information on spanning tree.
