| Is it just me, or does the level of aggregation within 207/8 really suck? I don't know what you mean. I only see /18s, /17s, /16s, and a couple /14s. A particular form of suppressing the advertisement of more-specific prefixes may be broken in someone's network, though. Known problem. Sean. P.S.: Hm, some of our customers seem to be announcing lots of unaggregated prefixes. I think people know how to avoid seeing these and in so doing pressure them to aggregate at the source.
