PBF with Egress loopback interface

L0 Member

I may be going about this wrong, but here's what I'm trying to accomplish, and this is the way I thought I could accomplish it.


I need to route all traffic from a specific zone/subnet to a routing instance, and load balance egress, with the exception of RFC1918 destinations.  My thought was to create a PBF rule to forward traffic to a loopback interface in the desired routing instance, where I have the appropriate routes configured, along with ECMP for load balancing.  This obviously doesn't work or I wouldn't be posting here.  The image below is a representation of what I am trying to do.

I've updated the config to use a different logical L3 interface (ae.200) due to loopback interfaces not being support for PBF, but I'm still not seeing any traffic flow.
