Daniel Thanks. I think I just now found all this in the code (too much code to look at :) Daniel Lezcano wrote: [ snip ] > >> >> If yes, then below approach will work.

This will add more overhead for sure. Does anyone have >>> comments on that or perhaps a better solution ? In the above solution, you'll need to account for wildcard binds as well. So, for l3, a match is ( !rcv_saddr || rcv_saddr == loc_addr). Should be easy enough with the right arguments. My suggestion is to make broadcast case use a different match macro/function. -vlad
