vxlan evpn data center interconnect through evpn mpls

[Daniel Blanco]

Good Morning

We want connect two DC using BGP EVPN solution having VXLAN feature in each site. We have doubts about if is possible extend VNI over a network with this approach :

EVPN-VXLAN <-> EVPN-MPLS <-> EVPN-VXLAN

We have found information with Juniper as solution (attached topology) but Cisco.

Is this solution feasible with Cisco ? Are there any documents to confirm it?

Thank you very much !!

Hi @Daniel Blanco 

The options available on Nexus switches are:

• EVPN to L3VPN (MPLS LDP) -  https://www.cisco.com/c/en/us/td/docs/dcn/nx-os/nexus9000/102x/configuration/vxlan/cisco-nexus-9000-series-nx-os-vxlan-configuration-guide-release-102x/m_configuring_seamless_integration_of_evpn_with_l3vpn_mpls_ldp.html
• EVPN to L3VPN (MPLS SR) - https://www.cisco.com/c/en/us/td/docs/dcn/nx-os/nexus9000/102x/configuration/vxlan/cisco-nexus-9000-series-nx-os-vxlan-configuration-guide-release-102x/m_configuring_seamless_integration_of_evpn_with_l3vpn_mpls_sr.html

If what you are looking for is simply interconnecting 2x DCs then you can consider VXLAN EVPN MultiSite, so your connectivity would be underlay agnostic:

• ciscolive technical presentation: https://www.ciscolive.com/on-demand/on-demand-library.html?search=vxlan%20multi-site#/session/1573153544426001Jy2f
• Config guide; https://www.cisco.com/c/en/us/td/docs/dcn/nx-os/nexus9000/102x/configuration/vxlan/cisco-nexus-9000-series-nx-os-vxlan-configuration-guide-release-102x/m_configuring_multisite_93x.html

Stay safe,
