I was wondering whether anyone running Junos on a current Broadcom chip

As you found out, XR won't forward the traffic using inter-VRF route
leaking if it has to do another recursive lookup in the next VRF. It
requires specifying the next-hop/interface or leaking the more specific
routes into the VRF. So if you have 0/0 pointing to null0 that's not going
to work. If

We were learning a default from an eBGP peer on the same node, so we

I tested the same by pointing 0/0 to another PE via the default VRF, and

Essentially same as an LT in Junos.
Not as elegant for sure, but should function.
IIRC, VASI support was only on the MSB (Multi Service Blade) on the XR
12000 platform.
Would this be a case where vasi-left and vasi-right interfaces are appropriate?

Hi all.
I've been racking my brain trying to implement an equivalent feature in
IOS XR 6.7.1 similar to Junos' "next-table" feature.
Essentially, I am trying to point all unknown destinations from within a
VRF toward the local global table for resolution. In Junos, it's as easy as:
