LINX for example permits very specifically IPv4 only, no multicast
including routing protocols etc, no mac broadcasts ie spantree.
I think theres a danger on very large switching fabrics that if youre not
specific things will happen that are detrimental to all members.. all
major switching problems I know of at LINX were caused by members doing
something not permitted by the rules...
Just because you -could- do something without the operator knowing doesnt
mean you should, the rules are there for everyones protection and I think
the fact that when people do things they shouldnt it has caused problems
speaks for itself in that respect.
