STP revisited

Hi all,

 

 

I know there has been some discussion in the forum on the topic of redundant config options with a pair of failover ltm's, however I have not seen any authoritative answer on the topic.

 

 

Is there any in-depth tech doc / whitepaper by f5 folks on the f5's implementation of the STP options available in the ltm config?

 

 

What are the recommended practices when deploying ltms in a highly available environment?

 

 

As a typical scenario - pair of two trunked 6500's and a pair of redundant ltm's - what are the implications of connecting each of the ltm's to each of the 6500's over the one-to-one scenario?

 

 

 

The way I see it, having a dual-homed linking on each of the F5's should give you the ability to do some intelligent vlan distribution over each of the trunked uplinks, such as having odd-numbered vlans taking a different trunk than even-numbered vlans.

 

 

Having a dual-homed config, which stp option should be enabled on the ltms?

 

 

 

Thanks,

    Hi Igor,

     

    ask.f5.com does have a solution article http://support.f5.com/kb/en-us/solutions/public/12000/300/sol12350.html?sr=14393242. Granted it's not a best practice guide but does provide some information about controlling STP and where to control it. There is even greater details found on the following link http://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/tmos_management_guide_10_1/tmos_stp.html1006923. Which is part of the TMOS Management Guide.

     

     

    I hope this helps.
