Not sure if anyone has made this work? We have had a horrible time finding documentation about whether or not it is supported - or how to configure it.
It seems TAC is struggling to provide a clear answer - and they are shying away from getting involved, as this is more of a design question.
Multicast in underlay is not an option, so we had been planning on using BGP/EVPN as the control plane protocol for VXLAN.
We have ISR4ks now, but are considering ASR1001-X or the Newer Catalyst Edge 8000 series routers.
Our sales rep seemed to think L2 VXLAN w/EVPN would be supported on these platforms. Though this seems unclear also.
We are strongly considering going with OTV - but even Cisco said that VXLAN is the way of the future - and would like to use it if it does what we need.
Any insight would be much appreciated.
Project Requirements, for reference:
- Unicast-Based Control/Data Planes
- P2MP
- Edge Redundancy within a site
- Load Balancing of VLANs to be spanned across the Edge devices within a single site (this is more a nice to have)
- Some kind of address learning so that once MACs are learned, traffic is no longer flooded to all nodes on the P2MP instance - at least for unicast traffic.
- Ability to pass customer multicast-dependent traffic (e.g. HSRP/VRRP/STP) over the P2MP DCI
