Re: route authentication

When I've tried asking about this I generally am told...
(a) it was perceived to cause performance issues,
(b) the routing software is so brittle that adding this feature
is considered too high a risk,
(c) they person at the other end
didn't know how to enable it so you couldn't do it [in other words,
there are urban legends about clueless network engineers too.]
(d) no hacker could figure out how to get into the infrastructure far
enough to attack that so it's not worth attacking (I consider this
excuse invalid but that's just my opinion. I can find Zebra and get
into a colo, I assume the bad guys could if they felt like it.)
This also comes up at NDSS periodically, I believe. You might check the
archives for that conference to see if there are papers on the topic.
I'm sure this august body can come up with some more data to identify

I would suggest that it is also ISP's who do not hire security consultants.
Consulting fees tend to come from departmental budgets, and almost
every network engineer I have ever met fancies themselves a security
expert. There isn't alot of incentive for them to get a third party
opinion, because of a lack of faith in the clue of most consultants, and
a general aversion to having anyone touch the delicate house of cards
many network engineers have constructed.
Maybe Cisco could add this as a default requirement of the configuration
that had to be explicitly disabled? In fact, it would be nice if all
protocol configurations had to have their authentication manually
