L3VPN currently doesn't react to VTEP IP changes (add or delete).
Whenever VTEP IP on a DPN is added or deleted , the next-hop IP of VMs in FIB entries on that DPN needs to be updated appropriately.
To know which all VM FIB entries to be modified , a new DpnToInterfaceList operational datastore (DS) is being introduced in InterfaceManager. InterfaceManager will update the DpnToInterfaceList operational DS , when VM is booted or deleted.
Whenever VTEP IP is added/deleted on a DPN , VPN would get a VxLAN tunnel event. VPN will query the InterfaceManager using RPC for a given DPNId to retrieve the list of VpnInterfaces(VM ports).
