Hi all,

Something that’s always bugged me about JunOS, is when you import a route from 
another VRF on JunOS, the attributes follow it - i.e. if it is a discard route, 
you get a discard route imported.
(Maybe this happens on other platforms, I honestly can’t remember, it’s been a 
while..)

This is an issue where you have a VRF with say a full table in it, and want to 
generate a default discard for other VRFs to import if they want internet 
access. Works great if the VRF importing it is on a different PE, but, if it’s 
local it simply gets a discard route, so packets get dropped rather than doing 
a second lookup.

You can solve this, sort of, with a next-table route, but things can get a 
little messy, so hoping for something more elegant.

I’m trying to figure out if there’s a better way to do this, i.e. to make it as 
though packets following leaked routes behave as though they are from a 
different router.

Anyone got any magic tricks I’ve somehow missed?
