Problem was in missing configuration on vSRX router for this nodes layout.
Here are missing commands: set protocols bgp group Contrail_Controller allow 10.109.5.0/24 set routing-options static route 10.109.5.0/24 next-hop 10.109.4.1 delete routing-options static route 10.109.4.0/24 next-table public.inet.0 set routing-options dynamic-tunnels dynamic_overlay_tunnels destination-networks 10.109.5.0/24
Also, there should be no nat between private networks in both node groups. GRE tunnels will not work over nat.
