4 way smlt / rsmlt - routing redundancy

4 way smlt / rsmlt - routing redundancy

I’m migrating our backbone to 4 vsp 8600 switches; two per location. for servers we are using a single layer 2 vlan that is spanned over both locations. for vlans that only exist in one location i use an rsmlt configration on the two corresponding vsp-switches to make sure there is no single point of failure.

i would like to create the same configuration for the server subnet, so that every vsp can act as their router. is it possible to create a 4 way rsmlt cluster between the 4 vsp for the server vlan? do i need to use vrrp for that? maybe a combination of both? whats the best practice for the above configuration?

I’m not so familar with VOSS (VSP) yet, but as far as I know, you only can create clusters with 2 nodes.

Then you need VRRP active-active or you use “Fabric Mode” with global-router - than all Cluster-Nodes act as one Router.
