VRRP problem

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.

Re: VRRP problem

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.
