regarding this document, we can configure an SRX firewall to loadbalance traffic between two or more equal-cost BGP advertised routes.
Nevertheless, it also says that you can only apply the per-packet load balancing export policy on the default routing instance, so it is not clear if that would apply to all routing instances or just to the default one. I couldn't find more information on this specific topic
Would someone be able to shed some light on this?
Thanks in advance,
It looks like this option is NOT available inside a routing instance so it could not be applied
Forwarding table load-balancing policy applies to :
1/ global routing table/GRT
2/ routing-instances of type "virtual-router" and "forwarding"
3/ It is also a prerequisite for multipath load-balance for routing-instances of type "vrf" where following additional knob is required for load-balancing along MPLS paths
set routing-instances BLAH routing-options multipath [vpn-unequal-path]
 and  are applicable for SRX in flow mode
 is applicable for SRX in packet mode
Brilliant, I did a quick & dirty PoC with vSRX and I see two entries installed in the forwarding table, but I could not find any document where it states that it is the intended behaviour, thanks for the confirmation, case  in your list is what applies in my case 🙂
Thank you sir!
