Solved: Re: VXLAN Underlay

Can we create a VXLAN underlay using VLAN interfaces instead of assigning IP-Address directly on the physical interfaces.

sp-i# sh ip int brief vrf all

IP Interface Status for VRF "VXLAN"(7)
Interface IP Address Interface Status
Vlan1800 10.18.16.225 protocol-up/link-up/admin-up
Po519.1809 10.18.16.209 protocol-up/link-up/admin-up

Hi @syed.saaud,

You should use a dedicated Layer 3 port to connect Leaf-to-Spine links for VXLAN underlay, otherwise forwarding encapsulation/decapsulation of VXLAN may not behave as expected.

You can add a new link for this purpose and once you have VXLAN up and running you can consider migrating this Vlan-interfaces to communicate over VXLAN to leverage its benefits.

Regards.
