One down side is the 20K IPv4/IPv6 Route limit. So no full routes and we also place a RT Filter on our VPNv4 sessions back to the core.

BGP-SD is your friend.

We hold a full IPv4/IPv6 table on each of them in RAM, which a handful of useful routes in FIB. Works great!

It means we can offer our customers a native eBGP session with a full BGP table from the ASR920, i.e., no need for an eBGP Multi-Hop session into the "clever" core.
