[c-nsp] GRE fragmentation and ASR9001

my google fu is failing me - so apologies if this is in easily findable

I want (need) to connect two ASR9001s over a GRE tunnel "across the
public Internet" (= outside MTU 1500), but need to provide a larger inner
MTU (~1600).  So, fragmentation and reassembly required.

Easy question: can the ASR9001 do that (in hardware, obviously)?

Pointers to documentation appreciated :-)

(Current XR release is 4.3.4, but knowing that "it is supported starting
in 5.17.4" would also be useful information)

USENET is *not* the non-clickable part of WWW!
