I was looking at the configuration guide for Cisco Cat-9300 switch (Fuji 16.9.x release). I noticed that all the examples/configuration are for VxLAN BGP EVPN. Does any one know if data plane learning is supported on this platform?
In absence of anything in the configuration guide, I went ahead and tried it on cat-9300 to see if this really works or not. It did NOT worked, my VNI's stay in the "down" state. Here is gist of the configuration.
I ensured the connectivity for underlay (both unicast and multicast)
This is lab setup so just one spine and two leafs. (all three cat-9300 with DNA advantage license)
- Stitched VLAN and VNI through following config
vlan configuration 200
member vni 100200
- Define NVE interface
interface nve1
source-interface Loopback1
member vni 100200 mcast-group 239.0.0.200
With this I was hoping that when traffic sourced from a host in VLAN 200 should be able to reach the host on the second leaf switch but it did not.
leaf01#show nve vni
Interface VNI Multicast-group VNI state Mode VLAN cfg vrf
nve1 100200 239.0.0.202Down L2CP 202 CLI N/A
The above output shows that VNI are down and mode is L2CP. I am not sure why its picking mode L2CP, I want to experiment with data mode learning. Perhaps it is not supported or am I missing something? I have tested underlay unicast and multicast and it is working fine.
