The problem with Trident 2 is that it doesn't route VXLAN.
which means in simple language that if we have a VLAN and we have a VTEP interface assigned to the same VLAN, we cannot have a SVI (Layer 3 interface on VLAN). So no routing, no ping, no ARP on the VLAN.
The solution to solve this issue is to somehow connect this VLAN to another Router. this router can be the switch itself or an external device, or even a Virtual router.
There is a method explained in LNV document to connect 2 ports of the switch. One port from the VLAN which has a VTEP (for example VLAN 15) and another port as a Layer 3 port (direct IP on the interface). With this solution we can provide routing to 1 VXLAN, and if we need to enable routing for more VXLANs, we need to connect more cables and create the same topology for other VXLAN.
Converting this port to a 802.1Q tagged port on both sides will create a loop and doesnt work.
What could be a good solution for VXLAN routing when we have multiple VXLANs?
I was thinking about using a Spine as external router and expand all the leaf VLANs to the Spin. but its a ugly solution.
