VRRP VMWare

[Docklands]

We have two 3750's running VRRP acting as the first hop routers for three 2960 access layer 2 switches.

Would it be possible to extend the VRRP service to two new ESXi 6 servers running VMWare, upon which is configured a virtual switch that supports 3 VLAN's. Each ESXi physical server has two NIC ports for connection to the virtual switch and uplinks to the 3750's, plus two others for SAN connectivity.

I am not sure if you can do VRRP on the ESXi, but even if you could, you would have to change your design and make ESXi to do all the routing between vlans for you and than have layer-3 links to the 3750s.

Hi Reza

We are not intending to run VRRP on the ESX server. The VRRP would be run on the 3750 interfaces but for this to work the virtual switches would need to pass the VRRP advertisements - down using multicast 224.0.0.18

The routing between vlans would be on the 3750.

Thanks

I'm slightly confused, are the two 3750's not able to talk to each other directly for VRRP to work? If not, is there a reason why you designed it this way?

What kind of virtual switch are you running?

Are you using a third-party non-VMWare virtual switch, that supports VRRP and you're trying to make it a member of the VRRP domain?

If the two 3750's were connected together then this would create a loop, which Spanning Tree would block.

The virtual switch is a standard switch as oppposed to a distributed switch.
