[lisp-interest] LISP-ALT and security

[Erik Nordmark <erik.nordmark@sun.com>]

My question to Vince at the mike in the explisp bof was:

Your example has a /24 EID prefix for the site on the right hand of the
slide.
When its ETR sends back a map-reply is there a mechanism that prevents
the ETR from using e.g., /16 instead of /24 as the prefix length in the 
map-reply?

AFAIU the security mechanisms in BGP doesn't help with this, since the
map-reply is sent directly back to the ITR.
