Hi Pekka,

Thanks for the reply.

so what is the significant of "rpf-check mode loose" on the interface when
I use feasible path?

Also what would the be the effect when I have a default route configured?

As far as I can gather from the juniper.net/techpubs is this:
"Loose mode—All packets are automatically accepted. For this reason, we
recommend that you not configure unicast RPF loose mode on interfaces that
the default route uses."

BTW, I am using junos 5.6R2.4
