Question

Virtual Wire Pair, HA and BPDU

Hi All, 

 

I'm trying to answer the following questions for a design and can't locate an answer in the docs:

 

- Does a Virtual Wire Pair forward Spanning tree BPDUs by default. 

- If running an Active/Passive HA cluster, how does the passive node deal with traffic that hits the VWP interface. (Does it drop it until it becomes active?)

 

Any help much appreciated, 

 

Jon

    1: no options exist to enable stp forwarding in the vwire cfg, You will need to do it in the interface members config system interface. I do not recall any means to craft a policy and to add BPDUs

     

    2: yes, any traffic on the inactive unit is ignored from processing But I have not ran VWP on a HA fgt. Maybe some one can chime in

    Thanks for the input Ken. Ideally, I don't want BPDUs to be forwarded as that simplifies my STP design overall! 

     

    I'll see if I can lab this out...
