As in, sometimes national operators will decline to speak bgp to (topologically) subnational operators, so that even when they present themselves with a regionally allocated public ASN and address space, these will not be accepted. I am not at liberty to identify specific cases, but if you look at recent-ish (RIR-era) ASN allocations that have never appeared in the routing table, you will come across (n) networks that fit this description.
Ah, that. Finding places with large incumbent telcos that want to preserve their monopoly, and typically have the local telco regulator in their pocket, is not hard at all .. this happens all the time there One possible reason would be that quite often the people there are not very capable at bgp at all .. so someone who's selling them routers gives them a static route to their upstream, then they give their downstream customers a word doc with a template that assigns the downstreams yet another static route ... Attempts at adding BGP and sometimes, MPLS, to those networks tend to produce interesting looking results. Especially funny example - someone who was a "senior admin" at a certain large asian ISP decided to ask Philip what a route map is, in a sanog tutorial on advanced BGP last year.
Another reason to approach with caution proposals to cede greater registry-like authority to national PTOs and regulatory authorities, IMHO.
Any such authority is guaranteed to be heavily abused to further existing monopolies -- Suresh Ramasubramanian (ops.lists () gmail com)
