Hi Joanna,

 

Today I did a bit different test with two standalone Big-IP which are working as Active/Active. I configured both machine in the same way and I have tried your proposal but as a result I still have Layer 2 Loop.

 

My Cisco switch Reported that as :

 

Oct 2 12:59:09.184: %SW_MATM-4-MACFLAP_NOTIF: Host 000c.2918.c3fd in vlan 122 is flapping between port Po1 and port Fa0/1

 

Oct 2 12:59:09.184: %SW_MATM-4-MACFLAP_NOTIF: Host 000c.2918.c3fd in vlan 123 is flapping between port Fa0/1 and port Po1

 

The only option which fixed that issue was when I have put my transparent mode = opaque. Which is not exactly L2 mode :) What is more I am still looking for some good document/book of which those three transparent modes are explained in more details. Could you propose me something?
