I said *could*. Don't take this for a design. There are lots of
details lacking.

We have stated before that LISP-ALT routers could cache
mappings. This can help with Map-Request latency. And if the
mappings are cached do to seeing Map-Replies or because they
are pushed with some other protocol, then so be it.
Does that mean the mapping system ( ALT overlay ) would spread some
outdated
mapping informations to the ITRs? Besides, will it make the ALT router
become another vulnerable place?
