Hi,
Let's assume there are two routing instances: R_VRF (vrf type instance) and S_FWD which is a Forwarding type instance. R_VRF imports routes from bgp and export from static and direct.
In doing Source Based Routing I'm using S_FWD and I need to set a default route where next-hop belongs to R_VRF remote end and learned via bgp.
Here is a simple configuration which might work for creating rib consisting of direct interfaces but not sure whether it will work when I want to specify a next-hop in S_FWD which is one of the bgp imported route under R_VRF.
Please find the topology attached.
root@JUNOS> show configuration routing-instances S_FWD

routing-options {
static {
route 0.0.0.0/0 next-hop 1.1.0.1;
}
