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?
