	Hello,

I am using GNS3 FRR appliance (in case it is important), in my GNS3
setting (before going to production) I want to use frr as a route
reflector for l2vpn evpn address family.

My setting is

router bgp 65000
 bgp router-id 10.102.33.1
 bgp log-neighbor-changes
 no bgp default ipv4-unicast
 bgp cluster-id 10.102.33.1
 neighbor boucle peer-group
 neighbor boucle remote-as 65000
 neighbor boucle update-source 10.102.33.1
 neighbor boucle capability extended-nexthop
 bgp listen range 10.100.10.0/24 peer-group boucle
 !
 address-family l2vpn evpn
  neighbor boucle activate
  neighbor boucle route-reflector-client
 exit-address-family
exit

My VTEPs (all in 10.100.10.0/24) establish a session with FRR and send
their EVPN routes (types 2 and 3).
However, FRR does not send the routes back to the clients

What did I miss ?
Should I check some kernel modules are present in the alpine linux on
which frr runs ?
