Re: New router feature - icmp error source-interface [was: icmp rpf]

Ah, but there's the rub...
ISPs who are "discreet" in how they wish their infrastructure to
be "viewed" will continue to engineer methods in which portions
are not visible to the public at-large.
Somehow, I don't think that will ever go away, so trying to tilt
at windmils w.r.t. (paraphrased) "...what interface an ICMP foo
is sourced from..." is, indeed... tiling at windmills, methinks. :-)
Cheers!

:) depends on the network I guess... I'm not sure it's going to tell you
anything about hops hidden by mpls lsp's that don't decrement ttl
though...
