I don't think it's fair to characterize it as a trend... I mean, ten
years ago, we were all (generalizing here) stupid enough to try these
tricks. Fortunately, smarter people have come along since, and learned
from our mistakes. There are also _vastly_ more people involved in the
industry now than then, so it comes as no surprise that there are still
some newbies trying this, despite all the lessons of the past. The good
news is that although they're a quantitatively growing group, they're a
shrinking _fraction_ of the whole. So that's evidence of some small
progress in the state of knowledge. Fight the law of conservation of
Bill - the argument seems like Proof by Rigorous Assertion:
I know it is a bad idea.
I really really believe it is a bad idea.
My friends say it's a bad idea.
Not one that I know says it is a good idea.
Therefore, and I can't emphasize this enough, in conclusion, it is a bad idea.
If what you are saying is true, I'd really like to hear just a couple of
insurmountable technical problems with WAN L2.5 infrastructure
interconnecting IX switches. For the sake of argument and to clarify the
discussion (Paul) let's make a few assumptions:
1) We are talking about an operations model where IX switches are operated
by a single company.
2) The IX switches are interconnected by MPLS by a transport provider
offering that service.
3) An ISP on one switch creates a VLAN for peering with ISPs on any of the
other switches. This ISP VLAN is only for peering with the ISP that created
this VLAN. Since he is paying for the VLAN traffic he has this right.
4) The cost of transporting the traffic between the switches is bourne by a
transport provider who in turn charges the ISP that created the VLAN in
I can articulate a half dozen reasons why this is a good idea. Please share
with us why this is a such a bad idea. If it has been tried before, it
would be helpful to point to specific the case and why it failed, the
technical failure scenario. I'd like to hear why/how it was worse by the
distance between switches.
