Hi all Do some providers out there have a problem accepting announcements that do not have route objects created. I am considering a fact that an ISP could have a /16 however it has not assigned this address to anybody, however they need to announce this in order to assign this to there customers.

I wouldn't count on an undocumented route being accepted. There are quite some ISPs (among them some of the typical transit AS) that will filter it.

If they advertise it, they should document it. Elmar. -- "Begehe nur nicht den Fehler, Meinung durch Sachverstand zu substituieren." (PLemken, <bu6o7e$e6v0p$2@ID-31.news.uni-berlin.de>) --------------------------------------------------------------[ ELMI-RIPE ]---

Yes. Without a route: object, there is no way to check whether the announcement is legitimate.

You don't need to have an assignment in the /16 to announce the whole allocation. But it must be allocated to the ISP in question, of course.

Hi Ofcourse the said network to be advertised is allocated and is registered as allocated to an ISP. However there is no route object for it ie say /20 of the network is assigned and the remaining part is not. Could is it right to announce the whole /16 yet only /20 has been assigned Wycliffe On Wed, 2005-03-30 at 17:11, Gert Doering wrote:

Yes. This is the whole idea of PA = provider *aggregateable* address space. But you still need a route object for whatever you announce. The route object is not tied to the actual assignments.
