Help on VxLAN EVPN Configuration on Catalyst 9500-32C

Attempting to configure VxLAN EVPN on a pair of Catalyst 9500-32C's for a Proof of concept. No joy so far. Been referencing these links:

https://community.cisco.com/t5/data-center-blogs/vxlan-evpn-configuration-example-n9k-p2p/ba-p/3663830

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9500/software/release/16-10/configuration_guide/lyr2/b_1610_lyr2_9500_cg/configuring_vxlan_bgp_evpn.html

BRKDCT-2949. 

Any suggestions? 

Main goal is to bridge a single VLAN and have 2 hosts communicate across the VTEPs.

Hello,

 

is this a partial config ? I don't see interface Loopback 0, which is bound to the NVE...

I've attached a more complete configuration for review. Thanks

Hi.
Did you find an answer to this?
I'm facing the same situation my self, and would love to see some working configs betweeen Catalyst switches.
All examples I have found involves Nexus switches, which I don't have.

Thank you

Official answer we received from Cisco was that at this time the 9k is not supported in the Spine function. We have put in a feature request for this role and are awaiting and *hoping* for support in a future release. If you put in a feature request as well this may help...;)

Regards,

Aaron

Thank you for your answer.
So it's not possible to set up between 2 Catalyst switches?

Beginner

Re: Help on VxLAN EVPN Configuration on Catalyst 9500-32C

the config is working based on ingress replication and not with multicast, 

please mark helpful if it helped.

Here also attached tested configs for 2 leaf switches.

My goal was just to do a POC for extending the VLAN across an IP network using EVPN on C9500.

The switches are directly connected but you can easily amend the BGP for multihop.

I hope that helps.

Hi,

 

I just wanted to know about 10.0.41.1 and 10.0.41.252 IPs in your configs configured as BGP neighbor IPs. Are these the layer-3 interfaces connecting both the switches?

 

Thanks.
