PTX router acting as MAC-VRF EVPN gateway will fail to forward traffic routed through interface.

Possible MAC-VRF config:

set interfaces et-0/0/2 unit 0 family ethernet-switching vlan members vn4004

set routing-instances evpn instance-type mac-vrf

set routing-instances evpn protocols evpn encapsulation vxlan

set routing-instances evpn protocols evpn default-gateway do-not-advertise

set routing-instances evpn protocols evpn extended-vni-list all

set routing-instances evpn service-type vlan-aware

set routing-instances evpn interface et-0/0/2.0

set routing-instances evpn vlans vn4004 vlan-id 4004

set routing-instances evpn vlans vn4004 l3-interface irb.4004

Incrementing sw.egnh.cfg_discard in:

>request pfe execute command "show cda trap" target fpc0

Need to configure VNI under MAC-VRF EVPN instance on PTX's:

# set routing-instances evpn-1 vlans vn4004 vxlan vni 204044
