Vxlan

[hs08]

Anyone know how to configure vxlan from cisco nexus to catalyst 9500? I need expand some vlan on nexus to c9500 in different location using tunnel interface so both location will share same vlan.

Hello
Require more information on your query, will this be L2 or L3 overlay of vxlan, meaning do you have multiple vlans you wish to extend that will require inter-communication or just a single vlan

hi @paul driver 

I have 3 VLAN on old location and this 3 VLAN should be extend in new location for VM migration where after VM migration done the ip address should be same.

So in my mind i will create VXLAN on my firewall and create tunnel to new location to extend the VLAN to new location.

2nd thing is in old location i use HSRP because i have 2 nexus as core switch and before VM migration done the nexus should keep act as the gateway.

While migration in progress and the VLAN can be extend using VXLAN, then i think in the core switch in new location i will configure HSRP also and this HSRP will joined to HSRP in old location for all VLAN.

After VM migration done i will shutdown VLAN interface on both nexus so the active gateway will handled by core switch on new location. What do you think?
