I experienced something similar to this in my lab and the issue was the image I was using. for some reason image 20.1 wasnt forwarding those routes, and wasnt advertising any-cast gateways (irb interface). I ran the same config on 18.4 and it worked! just a note

Hi Aaron.
I just learnt that CE packets (including ARPs) aren't even reaching my PE. So my issue is with my lab.
Apologies for having you spend time on this.
Regards,
Deepak

with my previously suggested changes in-place, please send the following output from pe1...
show configuration | display set | grep chass
show evpn database
show bridge domain instance EVPN-A
show bridge domain brief
show bridge mac-table instance EVPN-A

Thanks Aaron, but that didn't work either.
The PE is simply not forwarding the ARP nor advertising any Type 2 routes.

i did evpn differently. try this....
conf
delete interfaces ge-0/0/3 unit 610 family bridge
delete routing-instances EVPN-A
set routing-instances EVPN-A instance-type virtual-switch
set routing-instances EVPN-A route-distinguisher 1.1.1.1:101
set routing-instances EVPN-A vrf-target target:65512:101
set routing-instances EVPN-A protocols evpn extended-vlan-list 610
set routing-instances EVPN-A bridge-domains bridge-0610 domain-type bridge
set routing-instances EVPN-A bridge-domains bridge-0610 vlan-id 610
set routing-instances EVPN-A bridge-domains bridge-0610 interface ge-0/0/3.610
(and of course the other pe as well, changing pertinent items like RD)

Hello everyone!
I have just started learning EVPN (with LDP) and I have come across a roadblock with a most basic configuration. I was hoping someone can point out my misconfiguration.
I have 4 vMXs as follows:
CE1 ---- PE1 ---- P ---- PE2 ---- CE2
PE1 loopback is 1.1.1.1
PE2 loopback is 2.2.2.2
Some observations:
- I cannot ping from CE1 to CE2. I notice that the ARPs from CE1 do not reach CE2.
- The PEs exchange Type 3 EVPN routes but no Type 2s.
- The EVPN database and mac tables are empty.
