Dell 4048 running OS9 using Static VXLAN need help with Multicast so HSRP on Routers will work

I was able to get Static VXLAN working between two Dell 4048 on OS9 but I now need to be able to push multicast over it.  Specifically Hello packets from my routers using HSRP.

So all routers need to exchange HSRP hello packets from site 1 and site 2.

RTR-2

RTR-3
