    Hi, 

    I've tried on the labs to configure evpn with these configuration and topology (on the attachment).

    i'll try to lab this up later... i briefly looked it over.  i would expect to see lo0.0 in the LDP Protocol stanza.  also, i've implemented EVPN-MPLS between a couple DC's and used evpn route-instance instance-type virtual-switch.  i forget the difference between instance-type evpn and virtual-switch and the motivators for either.  i thought the reason i used virtual-switch was that I could get away with putting all my DC's vlans via one single EVPN.  seemed less adminstratively burdernsome IIRC.

    As Aaron stated, try adding the lo0.0 interface to the ldp and mpls hierarchy's.  

    @Aaron....type evpn is for vlan-based evpn and type virtual-switch is for vlan-aware evpn.  You are correct about multiple vlans in a single evpn instance using virtual-switch(aka...vlan-aware).​
