Re: IPv6 over vxlan+evpn Arista?

Nope the underlay can be v4-v4, just need to be able to carry the v4+v6 overlay to allow for migration of addresses.

Do you need to carry the v6 af in the underlay? I’ve used 6pe/6vPE to carry v6 over v4 next-hops in the overlay without 
issue, but can’t say I’ve tested a dual-stack vtep.

Hi all, was curious if anyone is doing dual stack v4/v6 over Arista’s implementation of vxlan / evpn (the inter-data 
center transport would be v4)?  They have plenty of references for v4 deployments but had to check on v6 support, which 
can make one nervous; they did confirm it’s supported.  Looking to leverage it as a way to migrate a dual-stack data 
center without re-addressing.

Thanks,
