Cisco ACI interesting multi site notes

At Cisco Live Europe 2016, I’ve heard a few interesting things about Cisco ACI. Down here, a few notes about the things I’ve heard (Non-nda):

  • Stretched fabric design: 3 site deployment is coming in Q2 2016. Sites are connected in a triangle
  • Multi-pod deployment is coming in Q3 2016
  • Multipod config is not managed by APIC and configured manually
  • Multipod uses 40 or 100Gb/s links
  • Multipod requires a higher MTU if using a service provider to handle VXLAN headers of 50 bytes
  • OSPF peering with service provider required
  • If you’re using DWDM or dark fiber WAN connections, the maximum RTT can be 10 msec
  • QoS at service provider to prioritize APIC cluster communication
