Re: routing table go boom

Hi,

As the ETR is not the final destination, it is subject to blackholing
after ETR, which means:

  The function in question can completely and correctly be
  implemented only with the knowledge and help of the
  application standing at the endpoints of the communication
  system.

Granted that it is no worse than multihoming by routing protocols.

But, it merely means that neither BGP nor LISP works "completely
and correctly".

Well, yeah, if your internal routing (behind the ETR) breaks then your network is broken...

Met vriendelijke groet,
Sander Steffann
