I agreed to the stipulation, in advance so I wouldn't get lecture #101, yet again. The issue here is that ASN's get around prefix filtering, to my understanding. If everyone had an ASN then we'd be right back to they problem that started prefix filtering in the first place, ever growing, and humongous, router tables. Legacy routers have problems with this. Damn! Now you gotten *me* to send lecture #101, sheesh! |;-) >I have a whole bunch of multi-homed >downstreams who have /21s or /20s - with their own ASNs. Should we just >give them more space? Or are they "not allowed" to multi-home? What am I >missing? Read the current ARIN pages. Unless I read them wrong, an ASN now requires a /19 to go with it. Anything less will not be approved. Existing /20's and /21's are under legacy grand-fathering. >>Roeland M.J. Meyer, ISOC (InterNIC RM993) > >TTFN, >patrick > >************************************************************** >Patrick W.
