VARP availability
-
Will TNSR support MLAG in the future? If so will the support for VARP also come into play?
MLAG + VARP is the modern approach to building datacenters so im hoping at some point in the future it will be available.

hi @michmoor may I ask what is your use case scenario? What are you trying to achieve?

@fractal_boy
VARP with MC-LAG allows for active-active forwarding. I don't want unused links in my datacenter. -
@michmoor what about if you run VRRP on TNSR routers and split your active virtual IP's (masters) between TNSR's. You won't have unused links in this case — something like this drawing.

@fractal_boy Sure but thats a bit legacy when it comes to datacenter design to be honest.
Having multiple VRRP groups isn't a modern design. VARP also wont have traffic run over the MLAG link but VRRP will.
Even thinking about multiple VRRP groups in my use case isn't scalable. I have over 100 SVIs in production and development environments. Its starts getting unwieldyedit:
Looking at your drawing, forget end user or servers downstream. Pretend its a dual homed switch or server that has a LAG up to the MC-LAG. It can send frames to either spine. That alone would warrant VARP.
