And the ASR99xx will take more of the upcoming line cards that get released.

Well, the ASR920 can only hold 20,000 IPv4 entries in FIB. So the MX104,
with the ability to do a full table, beats it there.

But then again, that is why the ASR920 is better-priced for such a role.
Hard to compete with that.
