    Hi all,

     

    one VRRP problem want to ask and i feel very confused.:smileyfrustrated:

     

    simple_diagram.png

    these two controller is Master/Local and Active/Passive Design. the controller uplink is trunk and user vlan gateway is on the swtich.

     

    i want to ask is that if the inter-link of the switch is broken, which controller will be become the active?

     

    any document can be provide??

     

    thx a lot.

    In your drawing, if the link between switches is broken, then you will have a "split brain" scenario with BOTH controllers acting as VRRP master.  VRRP is a ROUTER redunandcy protocol...not a LINK redundancy protocol.  So...I would advise each controller with dual links to each switch but be careful about spanning tree.
