Anything that depends on proper configuration of customer gear is inherently evil and dangerous. Of course, nobody ever creates an ethernet loop, redistributes the wrong prefixes, binds the wrong IP address, or anything like that, right? Hopefully I misread. Sharing your IGP with customers is very, very bad. Dynamic routes also need to be filtered at untrusted boundaries.
