BGP bug? Or feature… #nanog
I happened on a conversation on NANOG on issues with AS 0 with 0.0.0.0 as an IP, the issue was discovered with an update message. Read on for the full explanation from Ericsson:
To my knowledge – the only vendor which allows changing ASN in AGGREGATOR is Juniper, see “no-aggregator-id”, in the past I’ve tried to talk to Yakov about it, without any results though. So for those who have it configured – please rethink whether you really need it.
As for SEOS – understanding that this badly affects our customers and not having draft-ietf-idr-error-handling fully implemented yet, we will temporarily disable this check in our code. Patch will be made available.
