[c-nsp] VXLAN Unicast on Nexus 5600 or 9300

[Robert Hass]

Hi
I see that both - Nexus 5600 and Nexus 9300 platforms supports VXLAN which
relies on multicast in the network core. But are they support VXLAN relies
on unicast network ?

Maybe newer Nexus 9200 or approaching Nexus 9300-EX ?

Hi Rob

Here is a good read on vxlan control plane multicast/unicast.
http://blogs.cisco.com/perspectives/a-summary-of-cisco-vxlan-control-plane
s-multicast-unicast-mp-bgp-evpn-2

The 9ks will do mp bgp vpn , but not sure about the 5600 never used them.

This document doesn't provide any information what is supported on
different Nexus models.

I asked about unicast-VXLAN not "mp bgp vpn".

I know that 9300 can do multicast based VXLAN. But I need devices which can
do this using unicast as I have project where multicast will not be
implemented at L3 between VTEPs. I see that this is what Arista can do. But
due to politics we would stay with Cisco shop.

I believe Brian is referring to EVPN when he mentioned MP-BGP. This
resource may help, assuming you haven't seen it already:

The document explains what the three options are for cisco vxlan control
planes supported on various cisco platforms.
Multicast, unicast and mp-bgp evpn , pbb if you were.
I guess the “focusing on” section wasn’t enough for you, and my specifying
that the third option is supported on the 9ks was misunderstood.
Both the unicast and the mp bgp evpn do not require multicast, which is
better for you depends on what you want to do .

For the 9k take a look at
http://www.cisco.com/c/en/us/products/collateral/switches/nexus-9000-series-switches/guide-c07-734107.html

for the 5600 can’t help you but try the ciscolive sessions they are
available for free after registering and are really good about explaining
what features are available in which platforms etc.

For ingress replication you can do it with EVPN or statically. Have a look at the "Configuring BGP EVPN Ingress Replication” and "Configuring Static Ingress Replication” sections on:

http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/7-x/vxlan/configuration/guide/b_Cisco_Nexus_9000_Series_NX-OS_VXLAN_Configuration_Guide_7x/b_Cisco_Nexus_9000_Series_NX-OS_VXLAN_Configuration_Guide_7x_chapter_011.html#task_26EDB9B063DE4976BF020E94CE058CDD
