Re: Has PSI been assigned network 1?

The case you refered here is that among the 300 netcom routes the RS passed to your router, several of them are not originated from Netcom. As we discussed before, this was due to the particular routes registered in the PRDB with incorrect or out dated AS origin field. E.g. one of the routes we looked at was 192.33.137/24. The PRDB shows the following: route: 22.214.171.124/24 descr: NETCOM On-line Communications Services, Inc. descr: 3031 Tisch Way descr: Mezzanine descr: San Jose descr: CA 95128, USA origin: AS2551 comm-list: COMM_NSFNET advisory: AS690 1:2551(147) 2:1321 mnt-by: MAINT-AS2551 changed: [email protected] 941110 source: PRDB Note the field 'origin' here is AS2551 which is Netcom AS. While the BGP path shows AS Path: 2551 701 IGP. So there is an inconsistency here. Note, the data we used to test with you is from PRDB since RADB is not populated at this point (waiting for the community to register the information). Since the generation of AS690 configuration at this point does not rely on the AS origin filed, so not much effort being spent to clean up the data in this field. This actually brought an important point. That is, when ASs registering routes in RADB, please make sure the correct 'origin' field is registered and properly maintained. Also, it's important for ASs to start cleaning up the data in the PRDB especially the 'origin' field if they expect the data be transdered to RADB at some point. Second point is that your claim of Sprint seeing clean routes directly from Netcom could be flase because I believe Netcom advertises the same set of routes to you as to the RS. That means you get 192.33.137/24 from them as well unless Netcom applies a special exporting filtering when advertising routes to you. Just checked with Netcom engineer and they do not have special filtering with you. Please check at your router again or log the incomming advertisment from netcom to verify it. --Jessica
